4 Input/Output Functions
Input/Output
Overload detection and reporting will apply when the USB preamplifier is connected to USB. The USB
Preamplifier has its own overload detector which reports overloads to the instrument over USB. This
generates an error condition, "Input Overload;USB Preamp."
If, while the USB Preamp is connected to USB, a measurement is selected that does not support the USB
preamplifier, the "No result; Meas invalid with Preamp" error condition is generated.
MS
Sets an external gain/attenuation value for MS (Mobile Station) tests.

[:SENSe]:CORRection:MS[:RF]:GAIN <rel_ampl>
[:SENSe]:CORRection:MS[:RF]:GAIN?
CORR:MS:GAIN 10 sets the Ext Gain value to 10 dB
CORR:MS:GAIN –10 sets the Ext Gain value to –10 dB (that is, a loss of 10 dB.)
Does not auto return.
The reference level limits are determined in part by the External Gain, Max Mixer Level, RF Atten
This key is grayed out in modes that do not support MS.
This is unaffected by a Preset but is set to 0 dB on a "Restore Input/Output Defaults" or "Restore

[:SENSe]:CORRection:MS[:RF]:LOSS <rel_ampl>
[:SENSe]:CORRection:MS[:RF]:LOSS?
CORR:MS:LOSS 10 sets the Ext Gain value to –10 dB, and subsequently querying :LOSS will give 10
dB
CORR:MS:LOSS –10 sets the Ext Gain value to 10 dB, and subsequently querying :LOSS will give –10
dB
A positive value of <rel_ampl> in the above command means a loss and a negative value indicates a
gain.
Anytime :LOSS is set it sets :GAIN to the negative value of the parameter sent.
Anytime :LOSS is queried it gives the negative of :GAIN
