Instrument (M8195A)

To access the instrument settings, click M8195A in the tree view. If there is more than one instrument connection, there will be a corresponding number of Instrument listings in the tree view. The figure below shows the Instrument property grid when connected to an M8195A AWG.

Update to Instrument

Click this button to send the parameters to the connected instrument.

Update from Instrument

Click this button to retrieve the parameters from the connected instrument.

Preset

Click this button to set the signal generator to a factory-defined or user-defined state.

Refer to the signal generator's user's guide for information on setting a user-defined state.

DC Cal

Click the DC Cal button to execute an I/Q DC calibration to minimize errors associated with offset voltages.

DC Cal minimizes I/Q offset errors for a single frequency only and must be repeated if the signal generator's settings change.

Download a waveform to set the correct parameters for the target instrument and activate this button.

Power Search

Click the Power Search button to execute a manual power search calibration. This is an internal calibration routine that improves output power accuracy when the ALC is turned off. A power search is recommended for pulse-modulated signals with pulse-widths less than two microseconds.

1. Basic

Carrier Frequency

Range: 0 to 32 GHz

Set the value of the carrier frequency. Please note that the carrier frequency value only takes effect after downloading the waveform.

Carrier Scale

Range: 0 to 2.82843

Set the amplitude scale of the output signal.

Voltage

Range: 75 mV to 1 V

Set the amplitude of the output signal.

Reference Source

Choices: External | Backplane | Internal

Default: Internal

Double-click or use the drop-down menu to select the channel clock source.

Internal - Use the internal sample clock.

External - Use the external sample clock provided to the SAMPLE CLK IN connector on the M8195A front panel.

Output State

Choice: On | Off

Default: On

Double-click or use the drop-down menu to control the signal generator’s RF output state.

Sample Rate

Range: 54 GHz to 65 GHz

Set the internal sample clock rate, the samples in the waveform are resampled from the sample frequency taken from the waveform header to the sample frequency currently configured in the M8195A. Use abbreviations for faster entry (example: 1g = 1.0 GHz).

FIR Scale

Range: 0.1 to 1

Set the FIR filter scaling factor.
