3700S Release Notes V1.40 / May 2010 11
Version 1.41 Release - Noncritical fixes Series 3700 Firmware Release Notes
Some users may experience inappropriately degraded performance when using the Ethernet raw
socket and telnet sockets. The degradation may occur when a number of small packets are
exchanged across the socket. This is caused by the Nagle algorithm which delays Ethernet packets
for up to 200 mS waiting to combine small packets for network efficiency.
Resolution:
In most cases packet immediacy is more desirable than network efficiency. The Nagle algorithm is
now disabled by default to eliminate this delay. If necessary for Ethernet efficiency, use the lan.nagle
ICL to enable the algorithm.
PR41324 Models affected:
3706, 3706-S, 3706-NFP, 3706-SNFP
Symptom:
An error is not logged when an empty parameter string is passed to dmm.configure.delete(),

Version 1.40 installation notes
Upgrading to firmware version 1.40 requires special installation steps that are not required for other firmware
upgrades. Carefully perform the following procedures to successfully upgrade to version 1.40.
First, determine your instrument's current firmware revision. With the instrument powered on, press the SLOT
key. The instrument's current firmware version is displayed. Based on the current firmware revision, follow the
instructions in the appropriate section below.
Upgrading from firmware version 1.31a or any earlier version
Download the nk_5001607.nb0 and main_p37xx_0140k.CAB files from the
Keithley Instruments website (www.keithley.com).
To perform the upgrade:
10. Place the nk_5001607.nb0 and main_p37xx_0140k.CAB files in the root directory of a
blank USB flash drive (make sure drive size is large enough for the size of the upgrade files).
11. Ensure that the Series 3700 mainframe power is turned off, and then connect the flash drive
to the Series 3700 and turn on power to initiate the upgrade process.
NOTE The upgrade process will take three to five minutes and the instrument will reboot
several times during the process. Do not disturb the instrument until the normal front
panel display has been present for at least 30 seconds.

A new ICL function that allows inclusion of multiple channels in a single scan step has been added:
scan.addimagestep()
Usage:
scan.addimagestep(, [])
Where:
String specifying a list of channels
Optional string specifying a DMM configuration
This function adds a list of channels to be closed simultaneously in a single step of a scan. An optional
DMM configuration can be added to force the scan to take a measurement during the same step.
The scan.addimagestep function is an advanced command; the channel list parameter must
specify appropriate relays to support the requested DMM configuration, or an invalid measurement will
result.
Unlike the scan.add() function, paired channels and backplanes necessary for measurement are
not automatically added to the step. Use the channel.setpole() command to indicate if the paired
channel should be added or not. Backplanes assigned to channels by the
channel.setbackplane() command will not be added to the image step automatically. For
example, if a measurement is taken on a 4-wire ohms configuration without designating 4-pole with the
channel.setpole() command, the corresponding paired channel will not be added, and the
specified "dmm config" will not cause additional relay closures as it normally would. Backplane
channels that are needed for the desired measurement must be specified in the channel list
parameter.
If you have changed the pole setting on any of the channels in the list (using channel.setpole()),
an additional paired channel will be added or removed appropriately. For example, to ensure that the
proper channels close to enable a 4-wire measurement, set the pole setting in addition to using the
4-wire ohms DMM configuration.
When a DMM configuration (other than "nofunction") is specified, the instrument will take the
appropriate measurement based on the function set in the configuration; if no DMM configuration is
specified with the command, no measurement will be taken.
Example 1:
This example adds a single step that closes Channel 1001 and takes a DC voltage measurement.
Note that the voltage measurement will be inaccurate if this is the only step in the scan (because the
backplane channels are not closed).
scan.addimagestep("1001", "dcvolts")
