Version: 2x91 (Main Release)

Release date: 23-February-2021

!!! PATCHMASTER version 2x91 cannot open or export the old PULSE / POTPULSE data files any more. !!!

Conceptional Modifications:

Calibration

• Calibration Format
A new format of calibration record is now stored in the EEPROM of the EPC 10 (USB) amplifiers. Switching between version 2x91 and older versions require a re-calibration of the amplifier. The same applies for PATCHMASTER 2x91 and PATCHMASTER NEXT 1.2.

New Features:

EPC 10 (USB) Menu

• EIS Calibration
It is now possible to calibrate the Electrochemical Impendance Spectroscopy (EIS) method.

Spectrometers

• OceanView Spectrometers
OceanView Spectrometers using the OmniDriver.dll are now supported.

Protocol Editor

• Spectrometer Event
The new Spectrometer Protocol Editor Event can be used for setting acquisition parameters and for recording an optical spectrum.

Control Window

• Protocol / PGF Sequence Buttons
While data acquisition is running the protocol and PGF sequence buttons are disabled.

Configuration Window

• Spectrum Buffer Size
The buffer size for the Fourier Transformation can now be increased in order to extend the frequency range. In this context the option for a logarithmic compression was added as well in the Configuration Window (General Tab).

• Write Sweep Index
The "Write Sweep Index" option was included in the Configuration Window (Misc Tab). If checked, the index of the analyzed sweep is written into the Notebook Window together with the Analysis Results.

Batch Communication

• Analysis Parameters
A new Batch Command (DoGetOnlineParams) for reading out Analysis parameters has been added.

Pulse Generator

• Sweep Delay
As an alternative to "Sweep Interval" the option "Sweep Delay" was introduced. It defines the time from the end of one Sweep to the start of the next Sweep.

Analysis Window

• Stim. Frequency
The new Analysis Function "Stim. Frequency" has been added. It returns the frequency of a sine wave or square wave segment.

• Result Unit
For Analysis Functions (e.g. Math operations) which are not using the trace unit one can now define the new unit.

Fixed Bugs:

Calibration

• Probe Offset
Probe Offset saturated without reporting any error message during calibration. Fixed in v2x91.

Batch Communication

• MultiConnection Mode
The Batch Command "MultiConnection" did not work properly. Fixed in v2x91.

Equation Parser

• Sqrt Operation
The operaton "Sqrt(-1) returned "-1" instead of NAN. Fixed in v2x91.

Known Bugs:

None
