Introduction 1 M8195A Soft Front Panel must not be launched while using the instrument with M8070A. The M8070A is a licensed software, and thus requires a license to communicate with the M8020A/M8030A/M8040A hardware. You can either purchase an M8070A license to install on a dedicated host computer (M8070A-OTP) or one that can be installed on a network server that will be used as a license server for operating over a company network (M8070A-ONP, floating/networked).

Page 110: Option Sequencing For Extended Memory
For operation in instrument mode ‘Dual Channel’ or instrument mode ‘Four Channel’, all channels sourced from extended memory of M8195A behave identical with respect to sequencing. i.e. there is one sequence table available for the M8195A. Certainly the waveforms of the channels can be different for any segment number.
Page 111: Sequencer Granularity
Therefore, the sequencer has to play multiple samples within one sync clock cycle. The number of samples played within one sync clock cycle is called waveform granularity or segment granularity.

This means that each sample has its own bit signaling whether this sample is marked or not. The M8195A marker logic uses an edge based concept and therefore the sample based marker waveform is converted to an edge based marker waveform by the firmware of the instrument.

General Programming 6 IVI-COM Programming The recommended way to program the M8195A module is to use the IVI drivers. See documentation of the IVI drivers how to program using IVI drivers. The connection between the IVI-COM driver and the Soft Front Panel is hidden. To address a module therefore the PXI or USB resource string of the module is used.

Page 266: Resampling Modes
Resampling Modes Generally, the exact computation of the output record length leads to values, that don’t fulfill the granularity requirements of the M8195A waveform memory. Different resampling modes, which slightly modify the resampling algorithm, are offered to address this problem. The first term in brackets after the resampling mode is the enumerator to be used in the corresponding SCPI command.
