Known issues
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
When switching from one web application to another for the first time, a Java security warning window
similar to the one shown below is used to get the user’s permission. In the most recent versions of
Java (7u65 and 8u11), the security warning window appears behind the web browser when using
Internet Explorer. Until the security warning window is acknowledged, the web browser will appear to
be unresponsive. This only happens with Internet Explorer.
Workaround:
Enable the "Do not show this again for this app and web site." check-box prior to clicking the "Allow"
button.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
The first attempt to open TSB Embedded does not complete and users must click a second time for
the applet to start.
Workaround:
Click the TSB Embedded link again.

Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
If the user edits a script in TSB Embedded and clicks a non-applet link such as Sync Config prior to
saving, when they return to TSB Embedded the changes are gone and no script is displayed in the
editor.
Workaround:
Be sure to save your work before selecting another link.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
Upgrading or Downgrading to firmware version 1.54a might cause the instrument to lock-up.
Workaround:
Power cycle the instrument. On very rare occasions the instrument has been permanently disabled
and needs to be serviced.

Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
When identical relays are closed/opened in two or more consecutive scan-steps, the Channel Ready
trigger event is generated only when the first identical step is executed. It is not generated when the
subsequent identical steps are executed.
Workaround:
None.
Resolution:
This issue has been corrected.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.

are used.
Workaround:
None.
Resolution:
This issue has been corrected.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
Autoranged 4-wire resistance measurement of a 10 ohm resistor returns overflow on the 10 ohm
range when the lead resistance exceeds the Maximum 4WΩ Lead Resistance specification for the
range.
Workaround:
None.
Resolution:
This issue has been corrected. For the case of a 10 ohm resistor with excessive lead resistance, the
autoranging process will now bump the range up to the next highest range (100 ohms) and take the
measurement.

Enhancement:
Allow channel.open, channel.close, channel.getstate and channel.createspecifier to run while a
background scan is running. These commands can slow a scan down if they are called while the scan
is running. If there is no scan running then these commands function as normal.
channel.open can only be used on a slot that is not part of the scan list that is running. While
a scan is running channel.open will not accept “allslots” or “slot#” as the parameter. While a
scan is running channel.open will only accept a channel or list of channels.
channel.close can only be used on a slot that is not part of the scan list that is running.

Workaround:
None.
Resolution:
The TRIGGER functionality had been implemented, but was not reported in the device and interface
capabilities. The appropriate bits in the capability words are now set and resolve this issue.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
In the Java applet some of the file extension drop down boxes did not have a default extension
selected. This only happens when using Java JRE 7.
Workaround:
Using Java JRE 6.
Resolution:
The Java applet now requests a default file extension to be selected in the drop down box.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
In the Java applet the Pattern and Generate Report buttons were not working.
Workaround:
None.
Resolution:
The previous firmware release inserted an issue that caused these buttons to not work properly. This
has been corrected.
Models affected:
Models 3706A, 3706A-S, 3706A-NFP, 3706A-SNFP.
Symptom:
According to VXI-11.1 rule B.4.12, the status poll (device_readstb) should automatically clear the RQS
bit, but if a second status poll is executed, the RQS bit is still set. This means the RQS bit was not
automatically clearing.
Workaround:
Manually call a status clear after a status poll.
Resolution:
The RQS bit now automatically clears after a status poll.

NOTE: Firmware version 1.51 is the initial firmware release for the 3700A series and should not be installed on
non-A (for example 3706) models. For non-A series instruments, V1.41c is the latest firmware version. The
information provided below is only used to inform customers who had been previously using a model 3706 with
firmware release 1.41c.
