These commands apply to a fader setup when using a non-MIMO configuration. To be effective, a basic fader setup requires that the four commands shown below are executed. Some technologies require additional commands to set parameters, such as, antenna type, cell coverage, or parameters specific to a profile. Refer to Fader Channel Models for additional help on selecting these parameters.
Scenario– Profile selected depends on technology
Frequency Band (if applicable)
Numerical choices:
FSIMulator[1] – These choices correspond to the Master Setup used in the selected configuration. For non-MIMO configurations, a numerical choice is not required when using FSIM commands; only multi-user MIMO configurations require multiple master channels.
FADer[1]|2|3|4|5|6|7|8 – The fader number refers to the fader simulation block that you are configuring within the correlation group.
[:SOURce]:FSIMulator[1]:ALL:LOAD
This command downloads a dynamic fading file for each fading group when dynamic fading is enabled. The dynamic fading file to be used is selected using the :DFFilecommand.
[:SOURce]:FSIMulator[1]:DFADing ON|OFF|1|0
[:SOURce]:FSIMulator[1]:DFADing?
This command turns dynamic fading on or off.
[:SOURce]:FSIMulator[1]:DFFile "<filename>"
[:SOURce]:FSIMulator[1]:DFFile?
This command selects a previously created dynamic fading file to use when dynamic fading is enabled. Refer toUsing an Excel Spreadsheet Template for Dynamic Fading Setup for help in creating a dynamic fading file.
[:SOURce]:FSIMulator[1]:FADer[1]|2|3|4|5|6|7|8:FREQuency <val>
[:SOURce]:FSIMulator[1]:FADer[1]|2|3|4|5|6|7|8:FREQuency?
This command sets the carrier frequency to use for Doppler effects in the fading simulations. When the carrier frequency is changed, either the Doppler frequency or the vehicle speed is changed according to coupling specified in the Carrier Frequency Coupling command. It is not coupled automatically to any external instrument frequencies.
The value <val> is expressed Hz.
Range: 1
to 44 GHz
[:SOURce]:FSIMulator:FADer:FREQuency:EXTernal:UPDate

This command sets the mode of the fading simulation to normal (on), off, or pass through.
|
ON |
This choice sets the fader to apply impairments to the signal passing through. |
|
OFF |
This choice turns the fader off; no signal is transmitted through the selected fader block. |
|
THR |
This choice allows you to test the waveform behavior without applying impairments. It passes the signal through a fader block without applying fading to allow easier synchronization between the DUT and the PXB with the same fader backoff as with the fader enabled. |
[:SOURce]:FSIMulator[1]:FADer[1]|2|3|4|5|6|7|8:SEED "<val>"
[:SOURce]:FSIMulator[1]:FADer[1]|2|3|4|5|6|7|8:SEED?
This command sets the random number generation seed to be used for the waveform playback as a quoted string, for example, "0x1234". If it is set to zero, the generated fading will be different for each playback to provide randomness for each test. To reproduce the same fading environment for the same configuration as the last time it was played, use the same seed value (other than 0) each time.
