Parameters

`Use Internal Configuration block` — Use testbench internal configuration block
on (default) | off

Select to use testbench internal configuration block. Clear this parameter to specify your own configuration block.

Note

When using your own configuration block, parameters such as step size, fundamental tones, harmonic order, and simulate noise may affect the measured results.

`Simulate noise (both stimulus and DUT internal)` — Enable noise modeling in stimulus signal
on (default) | off

Select to enable noise modeling in the stimulus signal entering the DUT and inside the DUT.

Dependencies

To enable this parameter, select Use internal Configuration block.

`Input power amplitude (dBm)` — Input power to DUT
`-30` (default) | scalar

Input power to DUT, specified as a scalar in dBm. You can change the input power by entering the value in the text box or selecting a value using the knob. The specified input power represents the power available at the input ports of the DUT. The valid values are between -90 dBm and 60 dBm

`Input frequency (Hz)` — Carrier frequency of DUT
`2.1e9` (default) | scalar

Carrier frequency of the DUT, specified as a scalar in Hz. Input frequency must be greater than baseband bandwidth.

`Output frequency (Hz)` — Output frequency of DUT
`2.1e9` (default) | scalar

Output frequency of DUT, specified as a scalar in Hz. Output frequency must be greater than baseband bandwidth.

`Baseband bandwidth (Hz)` — Baseband bandwidth of input signal
`10e6` (default) | scalar

Baseband bandwidth of input signal, specified as a scalar in Hz. The value must be greater than zero.

`Source resistance (Ohm)` — Source resistance to measure DUT
`50` (default) | positive finite scalar

Source resistance to measure DUT, specified as a positive finite scalar in ohms.

`Load resistance (Ohm)` — Load resistance to measure DUT
`50` (default) | positive finite scalar

Load resistance to measure DUT, specified as a positive finite scalar in ohms.

`Show Response spectrum` — View response spectrum using a spectrum scope during simulation
on (default) | off

Select to view response spectrum using a spectrum scope during simulation.

Note

To view the response spectrum using a Spectrum Analyzer, you need a DSP System Toolbox™ license.

`Ground and hide negative terminals` — Internally ground and hide RF circuit terminals
on (default) | off

Select to internally ground and hide the negative terminals. Clear to expose the negative terminals. By exposing these terminals, you can connect them to other parts of your model.
