SR785 Dynamic Signal Anaylzer
Input Menu
The Input menu configures the analog signal inputs, the tachometer input, and sets the
parameters for capture playback.
Input Source
Select the measurement Input Source [Analog, Playback].
Analog uses the Ch1 and Ch2 front panel inputs as the source for all measurements. This
menu adjusts the input configurations for both inputs.
Playback uses the data stored in the capture buffer as the input for all measurements.
This selection is not valid until capture data has been acquired. This menu sets the
playback parameters. Capture is not available for swept sine measurements.
Both displays use the same Input Source for their measurements. The Analog/Playback
indicator shows the input source at the top of the screen.
Command: ISRC (?) {i}
Analyzer Configuration
Select the analyzer configuration [Independent Channels, Dual Channel].
Independent Channels allows the two displays to have different frequency parameters.
For instance, Display A could be set to full span while Display B showed a zoomed high
resolution display of a single spectral feature. In Independent Channels mode, only single
channel measurements are allowed. Dual channel measurements, such as frequency
response, or orbit, cannot be selected.
Dual Channel allows selection of all measurements, both single and dual channel.
However, in Dual Channel mode the two displays always have the same frequency
parameters.
