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)
