TRACe Subsystem
TVS600 & TVS600A Command Reference
2–227
TRACe:PREamble?
Transfers the data preamble for acquisition records or measurement results from
the waveform analyzer to your VXIbus controller. The data preamble includes
scaling and length information for the associated data record. The query does not
return data until pending acquisitions or calculations complete. Hence, the
synchronizing commands *WAI, *OPC, and *OPC? are not required.
The [SENSe:]DATA:PRE and CALC:DATA:PRE commands provide equivalent
functions to the command TRACe:PRE. For example, [SENSe:]DATA:PRE?
“XTIM:VOLT 1” is equivalent to TRAC? CHAN1 and CALC1:DATA:PRE? is
equivalent to TRAC? CALC1. The feed controls for CHAN1 to CHAN4 and
CALC1 to CALC4 are always enabled.
The source AATS is the Auto Advance Time Stamp record which is not
supported by the SENSe subsystem. The feed control for AATS is always
enabled.
For more information, refer to the TVS600 & TVS600A Series Waveform
Analyzers User Manual.
There are fixed feeds between the SENSe and TRACe subsystems.
[SENSe:]DATA:PRE? ”XTIM:VOLT 1” is equivalent to TRAC:PRE? CHAN1.
The feed control for CHAN1..4 is set to ALWays.
There are fixed feeds between the CALCulate and TRACe subsystems.
CALC1:DATA:PRE? is equivalent to TRAC:PRE? CALC1. The feed control
for CALC1..4 is set to ALWays.
REF1..10 are the reference waveform records. There are no sense functions
associated with these trace names.
[:DATA] is not accepted as a default node under DATA because the definition of
[SENSe:]DATA:PRE? and DATA[:DATA]:PRE? would be ambiguous.
