4 Input/Output Functions
Input/Output
BTS
Sets an external attenuation value for BTS (Base Transceiver Station) tests.
Key Path
Input/Output, External Gain
Remote Command
[:SENSe]:CORRection:BTS[:RF]:GAIN <rel_ampl>
[:SENSe]:CORRection:BTS[:RF]:GAIN?
Example
CORR:BTS:GAIN 10 sets the Ext Gain value to 10 dB
CORR:BTS:GAIN –10 sets the Ext Gain value to –10 dB (that is, a loss of 10 dB.)
Notes
Does not auto return.
Dependencies
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 BTS.
Preset
This is unaffected by a Preset but is set to 0 dB on a "Restore Input/Output Defaults" or "Restore
System Defaults->All"
State Saved
Saved in instrument state.
Min
–100 dB
Max
100 dB

Prior to A.02.00
Remote Command
[:SENSe]:CORRection:BTS[:RF]:LOSS <rel_ampl>
[:SENSe]:CORRection:BTS[:RF]:LOSS?
Example
CORR:BTS:LOSS 10 sets the Ext Gain value to –10 dB, and subsequently querying :LOSS will give 10
dB
CORR:BTS:LOSS –10 sets the Ext Gain value to 10 dB, and subsequently querying :LOSS will give –
10 dB
Notes
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
Preset
This is unaffected by a Preset but is set to 0 dB on a "Restore Input/Output Defaults" or "Restore
System Defaults->All"
Min
100 dB
Max
–100 dB
