12 SCPI Command Reference
channel and returns the Occupied Bandwidth in MHz.
MEASure[1]|2:ACP? Initiates a new RF capture on the selected E6610A RF RX
channel and reports the Adjacent Channel Power as 5 comma
separated values in the following order :
1. Carrier power in dBm
2. Adjacent lower channel power in dBc
3. Adjacent upper channel power in dBc
4. Alternate lower channel power in dBc
5. Alternate upper channel power in dBc
The command also creates a plot file of the trace data vs.
frequency over the configured bandwidth, with the fixed 3GPP
specified resolution bandwidth. Use the corresponding TRACE
command to read the trace data.
MEASure[1]|2:SEMask? Initiates a new RF capture on the selected E6610A RF RX input
and performs a spectrum emission mask test on the carrier at
the configured frequency and bandwidth, using the configured
SEM mask format. The command returns 12 parameters as
follows:
1. A textual result of "PASS" or "FAIL" showing if the emissions
complied with the mask or not.
2. Emissions level in Mask region 5, at a lower frequency than
the carrier
3. Emissions level in Mask region 4, at a lower frequency than
the carrier
4. Emissions level in Mask region 3, at a lower frequency than
the carrier
5. Emissions level in Mask region 2, at a lower frequency than
the carrier
6. Emissions level in Mask region 1, at a lower frequency than
the carrier
7. Emissions level at the carrier frequency
8. Emissions level in Mask region 1, at a higher frequency than
the carrier
9. Emissions level in Mask region 2, at a higher frequency than
the carrier
10. Emissions level in Mask region 3, at a higher frequency than
the carrier
11. Emissions level in Mask region 4, at a higher frequency than
the carrier
12. Emissions level in Mask region 5, at a higher frequency than
the carrier
The command also creates a plot file of the spectrum emissions
vs. frequency (including the scaled SEM mask) trace data over
the configured bandwidth. The resolution bandwidth used is
varied according to the 3GPP specification for the selected SEM
