12 SCPI Command Reference
measurements are made. In addition, the capture
process needs to be enabled for each input using
the SENSe<1|2>:RADio:CAPTure:STATe ON
command prior to starting a data capture.
SENSe<1|2>:RADio:STATe? Queries the state of the selected RF RX input. Result is
ON or OFF.
SENSe<1|2>:RADio:LEVel <value in dBm> This command sets the expected RF power level
from the RRH in dBm. This level will be combined
with the SENSe<1|2>:RADio:CORRection setting to
inform
the E6610A of the approximate input power to
expect, so it can adjust its input attenuators and
avoid any damage to the input circuitry. The
command to set the attenuation/correction
should be sent prior to this command to set the RF
power level. For example, if the power at the RRH
Tx port is +40 dBm and the
SENSe<1|2>:RADio:CORRection is set to 50 to
indicate that there is 50 dB external attenuation in
the path from the RRH Tx to the RF RX port in the
E6610A, the E6610A will adjust its attenuation
based on an expected input level of -10 dBm.
WARNING: If the actual input RF power is more
than 10 dB above the level set using this
command, damage to the E6610A's detection
hardware may occur.
SENSe<1|2>:RADio:LEVel? This command will return the currently configured
RF power level for the selected RF RX input.
SENSe<1|2>:RADio:CORRection <value in
dB> Sets the amount of external attenuation on the
selected RF RX input in dB. This command should
be sent before sending the command
SENSe<1|2>:RADio:LEVel.
Note: The E6610A will automatically compensate
the measurement results to account for any
external losses configured using this command.
For example, consider the case where the
correction is set to 10 dB and an
MEASure:AVGPower? result is requested. If the
actual RF power measured at the E6610A's RX
input was 0 dBm, then the E6610A would correct
for the external loss that has been configured and
10 dBm as the measurement result.
This parameter defaults to 0 dB and in this
configuration, the E6610A will report the RF power
as measured directly at the chosen RX input.
SENSe<1|2>:RADio:CORRection? Queries the current setting of the external
attenuation on the selected E6610A RX input.
