Firmware features added:

Instrument firmware versionFeatures added


Minor bug fixes.


Added two new excitation frequencies (11.6 and 8.12 Hz) for the measurement and control channels. Added support for cubic spline curves.


Minor bug fixes.


Corrected the operation of the *CLS command. This command should clear out the ESR and STB registers but instead it was clearing out ESR and SRE.

Changed the operation of the OVLD (overload) bit in the STB register. The OVLD status bit in the STB register is now a summary (OR condition) of the overloads for the control channel (if enabled) and the current scan channel. If there is an overload on a different scan channel, then it will not be included in the OVLD bit until it becomes the active scan channel.

Corrected 370 emulation problems with the following commands: ZONE, FREQ, RAMP.

Corrected rounding/resolution problems on the following command queries: MOUT?, AOUT?, HTR?

Corrected the filter used for the input readings (both control and measurement inputs). A reading offset can be accumulated if the filter has not been reset for an extended time (on the order of a day). The filter will normally be reset if a reading exceeds the filter window or if the scanner changes channels (on the measurement input).
