SOURCE Subsystem Commands
The SOURCE:RADIO commands configure either the RF TX1 or RF TX2 output on the
E6610A, while the SOURCE:CPRI commands configure the CPRI TX1 or TX2 outputs.
Command Description
SOURce<1|2>:RADio:POWer <level> Sets the desired RF power level at the RRH test port in
dBm. The E6610A will automatically adjust the level of
RF power output at its RF TX port to account for any
external losses configured using the
SOURce:RADio:CORRection command, so this
correction command should be sent before setting
the RF power level.
SOURce<1|2>:RADio:POWer? Returns the RF power level currently configured for
the selected E6610A RF TX output in dBm.
SOURce<1|2>:RADio:MODE CW |
MODULATED Sets the selected E6610A RF TX output to be CW or
modulated signal format
SOURce<1|2>:RADio:MODE? Returns the currently configured mode for the
selected E6610A RF TX, either CW or modulated.
SOURce<1|2>:RADio:STATe
ON|OFF|1|0 Sets the state of the selected E6610A RF TX output to
be ON or OFF (1 or 0).
SOURce<1|2>:RADio:STATe? Returns the currently configured state of the selected
E6610A RF TX output (ON or OFF).
SOURce<1|2>:RADio:FREQuency
<value in kHz> Sets the center frequency of the selected E6610A RF
TX to the chosen frequency (value in kHz).
SOURce<1|2>:RADio:FREQuency? Returns the currently configured center frequency of
the selected E6610A RF TX output in kHz.
SOURce<1|2>:RADio:CORRection
<value> Specifies the amount of external attenuation (in dB)
on the selected E6610A RF TX path. The E6610A will
automatically compensate the level of RF power
output at its TX port to account for any external losses
configured using this command. This command
should be sent prior to the command
SOURce<1|2>:RADio:POWer.
For example, if the correction is set to 20 dB and a
SOURce:RADio:POWer of -80 dBm is requested, the
E6610A will transmit -60 dBm at its RF Tx output port,
so that after the external losses of 20 dB are taken
into account, the power level presented to the device
under test will be -80 dBm.
SOURce<1|2>:RADio:CORRection? Returns the value of the currently configured
correction for the selected E6610A RF TX output in
dB.
SOURce<1|2>:RADio:ARB:TRIGger
<value> This command is used to set the trigger delay for the
selected E6610A RF TX output, which determines
when the waveform playback starts with respect to
the LTE airframe tick. This allows the user to account
for propagation delay in any circuitry connected to the
