246 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
14 Measure (Spectrum Analysis Mode)
Remote Command Notes:
The main channel power is returned in the current amplitude units, and the lower and upper
channel results are always returned in dB.
Example:
FETC:ACP? or MEAS:ACP? or READ:ACP? commands return the scalar results of
main channel power, lower channel power (relative), and upper channel power (relative) if
only one offset is set to on and the Radio Standard is set to None. Otherwise, 28 values are
returned. If Meas Type is Total Power Ref, these are the main channel power in dBm and in
dBc from the carrier (0 dBc) each repeated, followed by the absolute and relative power
levels for each lower and upper offset if Meas Type is Total Power Ref. Otherwise they are
not
specified, or
n=1
Meas Type = Power
Spectral Density
Reference
Returns 28 comma-separated values, in the
following order:
Center Frequency - relative power (dB)
Center Frequency - absolute power (dBm/Hz)
Center Frequency - relative power (dB)
Center Frequency - absolute power (dBm/Hz)
Negative Offset Frequency (1) -
relative power (dB)
Negative Offset Frequency (1) -
absolute power (dBm/Hz)
Positive Offset Frequency (1) -
relative power (dB)
Positive Offset Frequency (1) -
absolute power (dBm/Hz)
...
25. Negative Offset Frequency (6)
- relative power (dB)
26. Negative Offset Frequency (6)
- absolute power (dBm/Hz)
27. Positive Offset Frequency (6)
- relative power (dB)
28. Positive Offset Frequency (6)
- absolute power (dBm/Hz)
The center frequency relative power is relative to
the center frequency absolute power, and therefore
is always equal to 0.00 dB.
