3.4 HRP UWB Demodulation Measurement
This measurement provides the capability of demodulating the HRP UWB signals
and displaying the demodulated signal both in the time domain and in the frequency
domain.
Measurement Commands
The general functionality of "CONFigure" on page 2431, "INITiate" on page 2432,
"FETCh" on page 2432, "MEASure" on page 2434, and "READ" on page 2433 are
described in the section SCPI Operation and Results Query in the topic
Programming the Instrument.
Note that, in general, :CONF:<Measurement> resets the specified measurement
settings to their defaults. X-Series permits the addition of the NDEFault node to the
command, which prevents a measurement preset after a measurement switch.
The tables below list setup commands for this measurement and queries to retrieve
results.
Command Function
:INITiate:HUWB
Initiates a trigger cycle for the HUWB measurement, but does not return any data.
You must then use :FETC:HUWB[n]? to retrieve data
Does not change any measurement settings
:CONFigure?
Returns the long form name of current measurement, in this case, HUWB
:CONFigure:HUWB
Selects HUWB measurement with Meas Setup settings in preset state
See "Meas Preset" on page 500
:CONFigure:HUWB:NDEFault
Selects HUWB measurement without affecting settings
The following queries are used to retrieve data. The type of data returned depends
on the value of n.
Command Function
:FETCh:HUWB[n]?
Retrieves the data defined by n
:MEASure:HUWB
[n]?
Switches to HUWB measurement, restores default values, starts the measurement, then retrieves
the data defined by n
:READ:HUWB[n]?
Starts the measurement, then retrieves the data defined by n
Remote Command Results
The following table lists the results returned by the FETCh, MEASure, and READ
queries above, indexed by subopcode n:
n Return Value
0 Returns unprocessed I/Q captured trace data, as a series of trace point values.
The I values are listed first in each pair, using the 0 through even-indexed values.
