Measurement Setup Parameters
Channels: From the menu Input > Channels, available options are:
1 channel through n channels (n depends on your digitizer model),
I+jQ (IN1+jIN2)
The custom channel configuration can be used to specify a non-standard mapping
between the digitizer input and the VSA logical channel. The default mapping of the
logicals channel to the digitizer inputs is:
Logical Channel
1
2
From the menu Input > Analog the following parameters can be set:
Range: Thedigitizer offers several full scale range. Please refer to
product datasheet for details.
Coupling: DC
Input Impedance: 50 Ohms.
Connection: Single Ended.
The frequency measurement parameters can be configured from the MeasSetup >
Frequency menu.
Frequency: The default setup is shown below as example.
Model Option
-SR2
Span: The maximum span is dependent upon both the sampling rate and
the analog bandwith of the particular digitizer model.
Model Option
-SR2 -F05
-SR2 -F10
The maximum span is obtained with following formula:
Maximum Span = Min( Sample Rate / 2.56 ; Analog Bandwidth)
The analog bandwidth depends on the digitizer, the option (-Fxx) and interleaving
mode (see product datasheet for details).
Maximum span depends also on the digitizer sampling rate.
