Operating Instructions-7M13
OPERATION
The 7M13 Readout Unit will operate in any plug-in compartment of a Tektronix 7000-series
oscilloscope equipped with a readout system . The 7M13 Readout Unit is activated by pressing it firmly into
position in a compartment of the oscilloscope mainframe . The display will appear on the CRT in the
position associated with the selected plug-in slot .
Channel Selection
UPPER
The WRITE pushbuttons provide channel selection . Channel 1 is selected by pressing the
pushbutton and channel 2 by pressing the LOWER pushbutton . These pushbuttons illuminate (in
compatible mainframes) to indicate the position selected .
Erase
The ERASE pushbutton must be pressed before entering data for display . This clears the selected
channel of any previously entered data and resets the 7M13 circuits to accept new data . The ERASE
pushbutton does not affect the camera counter display .
Data Display
Both channels have a display capacity of ten characters or spaces . Each character, including the decimal
point, requires one space in the display .
Each character pushbutton switch is labeled with the character it selects . Pressing any of these switches
causes its associated character to be displayed on the CRT . Spacing between characters or words is provided
by the SPACE pushbutton . Pressing this switch causes the display to skip one space .
Subsequent pressing of a character switch when all ten display spaces are filled will cause the tenth space
character to be replaced with the newly selected one .
Modify
The MODIFY pushbutton allows the last entered character to be changed without erasing the display .
This switch must be pressed and held while the new character switch is pressed . The last entered character
will then be replaced with the newly entered one .
Camera Counter Operation
The CAMERA COUNTER is activated by pressing the PUSH ON switch . The switch locks in and
illuminates when the CAMERA COUNTER is selected . This causes the 2-digit camera count to be displayed
in channel 2 .
The camera counter display is set to zero by pressing the (P)RESET switch . Once this is done, two zeros
will appear in the display as the camera count . If it is desired to set the camera count to some number other
than zero, the (P)RESET switch must be pressed and held while the desired number is entered . When
presetting the CAMERA COUNTER, the first number pressed will be entered as the tens digit and the
second as the units digit.
Operating Instructions-7M13
A maximum of eight additional characters can be entered in channel 2 when the CAMERA COUNTER is
activated . The camera counter display appears in character positions 4 and 5 of channel 2 when no other
data is present. As other data is entered, the camera counter display will automatically shift to the right .
The camera count can be advanced by pressing the ADVANCE pushbutton . Each time this button is
pressed, it advances the camera count by 1 .
The camera count can also be advanced by the action of a camera shutter . This is accomplished by using
the remote advance cable provided with the Readout Unit. The cable is connected to the normally open
jack of any Tektronix C-50 series camera and to the SYNC IN jack on the front panel of the Readout Unit.
When connected in this manner, the camera count will be advanced each time the camera shutter is
operated .
An optional remote advance cable, Tektronix Part Number 012-0364-01, is available on special order.
This cable permits connection of the CAMERA COUNTER SYNC IN jack to cameras with ASA shutter
connectors .
Section 2-7M13
THEORY OF OPERATION
INTRODUCTION
The 7M13 Readout Unit provides front panel operation of the readout system of any Tektronix 7000
series oscilloscope . It will operate in any plug-in position in the oscilloscope mainframe . The readout
display will appear on the CRT in the position associated with the selected plug-in compartment . Refer to
the mainframe service manual for the readout system circuit description and to diagram 1 in this manual for
the following circuit description .
. THEORY OF OPERATION
The WRITE pushbuttons select either the UPPER or LOWER (channels 1 and 2 respectively) memory
IC's for data storage . This routes the output of U202B through U168C for the UPPER and through U168D
for the LOWER channel selection. The signal is then presented to the appropriate column and row memory,
write enable inputs .
Each channel has a ten character capacity . As each successive character pushbutton is pressed, the
output of U132C causes U198 to advance its count to the next character position address . This continues
until all character positions are filled . U129B locks in the tenth position and is reset by pressing ERASE .
Pressing a character button when all ten positions are filled will cause the tenth character to be replaced
with the newly selected one .
The ERASE pushbutton, when pressed, fires single-shot U170B. The pulse from U170B clears U129B
and allows pulses derived from time slot information (output of U163D) to be presented through U168A,
U168B, and U132C to U198 (address-to-memory) . The output of U168B is also presented to the
write-into-memory circuits. These pulses cause U198 to count through all data addresses, while the
write-into-memory circuits allow the data present on the data inputs to the row and column IC's to be
written into the memories. No data is present on the inputs to the memories during ERASE . This "no data"
condition is interpreted as a skip command and results in a blank display for that channel . When single-shot
U170B returns to its normal state, it triggers single-shot U170A to reset U129B and the address-to-memory
counter, U198 .
Time slot pulses 2 through 10 are routed through Q177 and 0185 . These pulses are used to advance
U195, the read from memory address IC . Time slot 1 is routed through Q190 and is used to reset U195 at
the end of each count .
The address multiplexer (U200) determines which address, either time slot (output of U195) or data
(output of U198), will be directed to the memory select inputs. Normally, U200 directs time slot addresses
to these inputs for data readout, however, when a character pushbutton is pressed on the front panel of the
Readout Unit, the output of U202A causes the multiplexer to switch and read the address at the outputs of
U198.
Pressing a character button supplies ground closures to the inputs of U109 (column data) and U103 (row
data) . U109 and U103 are decimal-to-BCD converters . They generate the coded character information
presented to the memory data inputs ; column data to U280 and U260, row data to U240 and U220 .
Since all characters generate column data, the outputs of U109 (through diodes CR109, CR110, CR111,
and CR112) are used to inititate the write-into-memory command signals and to trigger the
address-to-memory . This signal, through U202A, is also used to switch the address multiplexer (U200) from
the read-from-memory address (output of U105) so that data stored in the memories can be read and
Theory Of Operation-7M13
displayed on the CRT. Only when a write command signal is present (output of U202A) can U200 read the
address present at the output of U198 . When the address-to-memory command signal is presented to the
memories, information present on the data inputs to the memories will be accepted for storage. Once this is
accomplished, U200 returns to reading the addresses from U195 (time slot information) and the newly
stored character is displayed on the CRT.
The MODIFY pushbutton permits interruption of the address advance pulse (output of U132C) . When
pressed and held, the MODIFY pushbutton allows the last entered character to be changed regardless of its
position in the display.
The SPACE pushbutton generates only row data, therefore, CR102 is used to allow generation of the
write-into-memory and associated signals through the output of U168B. This allows data for space
generation to be stored in the memories and displayed in the same manner as a character.
The camera counter works only through the lower, channel 2, display position . When the camera
counter is selected, it causes time slots 9 and 10 to be reserved for the camera counter display. This is
accomplished by the output of U166A which blocks the memories during these time slots to allow camera
counter information from U159 (units digit) and U161 (tens digit) to be displayed .
Pressing (P)RESET clears U129A, blocks U166D and resets U154 and U157 to zero. The output of
U105E activates the current necessary for zero character generation when no data is present at the outputs
of U159 and U161 . Pressing a number pushbutton (while pressing and holding the (P)RESET pushbutton)
enters that number in the tens position, U157, which is enabled by U132B. The action of U122, when the
number pushbutton is pressed, causes U129A to switch . This allows the next number to be entered as a
units digit in U154-now enabled by U132A.
Camera counter data is presented to the inputs of U265 during time slots 9 and 10 . U161 is activated by
U163C during time slot 9. U159 is activated during time slot 10 by U163B.
The ADVANCE pushbutton, when pressed, provides a ground closure for advancing the camera count .
The SYNC IN jack provides the same function when connected to a camera shutter.
The output of U202A provides an over-ride of the blocking action of U166A during time slots 9 and 10
when the camera counter is selected . This permits entry of other information during these time slots. The
camera counter display is not erased by the ERASE pushbutton .
The outputs of U225, U245, U265, and U285 determine which characters are generated in the readout
system . Refer to the schematic diagram for the functional identification of these IC's . These IC's convert
the BCD input to an output current . This is accomplished by using the BCD inputs to select current inputs
to pins 10, 11, 12, 13, and 14 which are used either singly or combined to produce the proper current
outputs (row and column) for character generation in the readout system .

measurement from the effects of related circuitry . Fig . 3-1 shows the lead configuration of the
semiconductor devices used in this instrument .
1 . TRANSISTORS AND INTEGRATED CIRCUITS . The best check of transistor and integrated circuit
operation is actual performance under operating conditions . If a transistor or integrated circuit is suspected
of being defective, it can best be checked by substituting a component known to be good . However, be sure
that circuit conditions are not such that a replacement might also be damaged . If substitute transistors are
not available, use a dynamic tester, such as Tektronix Type 576 . Static-type testers may be used, but since

Maintenance-7M13
2 . DIODES: A diode can be checked for an open or shorted condition by measuring the resistance
between terminals . With an ohmmeter scale having an internal source of between 800 millivolts and 3 volts,
the resistance should be very high in one direction and very low when the leads are reversed .
Do not use an ohmmeter scale that has a high internal current. High currents may damage the
diodes.
3 . RESISTORS. Check resistors with an ohmmeter . Resistor tolerance is given in the Electrical Parts
List. Resistors normally do not need to be replaced unless the measured value varies widely from the
specified value.
4 . CAPACITORS. A leaky or shorted capacitor can be detected by checking resistance with an
ohmmeter on the highest scale . Use an ohmmeter which will not exceed the voltage rating of the capacitor.
The resistance reading should be high after initial charge of the capacitor . An open capacitor can best be
detected with a capacitance meter, or by checking whether the capacitor passes AC signals .
