10.3 Remote Control of Naveform Processing Functions
Remote control of the waveform processing is essentially achieved with
extensions of existing commands. No processing occurs if the
corresponding TRACE FUNCTION E (TRFE) or TRACE FUNCTION F (TRFF) is
(see Section 7.6.3). This -is also true even if the -SCREEN has been
turned OFF. Averaging can be stopped and continued by switching from
TRIG MODE NORM to TRIG MODE SINGLE and vice versa. Of course, it can
also- be stopped by turning its corresponding trace OFF. An average or
an accumulation of extrema can be reset by a new command,
AVERAGE RESET. A new function or new processing parameters are defined
with extensions to the command REDEFINE. In addition, the command
INSPECT allows some characteristics of the waveform to be known before
it is read out.
i) AVERAGE RESET (ARST)
The
accumulated average or extrema of the SELECTed trace is reset.
This command can only be applied to FUNCTION E or to FUNCTION_F.
The 9400A sets the ENVIRONMENT ERROR:
- if the SELECTed trace if OFF.
- if the SELECTed trace is neither FUNCTION E nor FUNCTION F.
The INSPECT commands of Section 7.6.5 have been extended to cover the
inspection of FUNCTIONS E and F by including the following mnemonics:
2) INSPECT (INS)
< FUNCTION E.LIMIT (FE.LI)
< FUNCTION F.LIMIT (FF.LI)
instructs the 9400A to return a character string containing the
lower and upper address limits of the current waveform,
or
INSPECT (INS) , < FUNCTION E.NSWEEPS (FE.NS)
< FUNCTION-F.NSWEEPS (FF.NS)
instructs the 9400A to return a character string containing
number of acquired sweeps (in averaging and extrema),
the
or
INSPECT (INS) ,
< FUNCTION E.INTVAL (FE.IV) >
< FUNCTION-F.INTVAL (FF.IV)
