7.6.2 Acquisition Parameter Commands
i) TIME/DIV (TD)
, <? >
< [ 2 NS to I00 S ] >
Other available suffixes are: US (Bsec, microseconds) and MS (msec,
milliseconds).
The 9400A sets the VALUE ADAPTED bit:
- if an out-of-range value is given.
- if a value outside the incremental steps of i, 2, 5 is given.
Examples:
TD = ?
TD 20 US
TIME/DIV 12 MS
Instructs the 9400A to send the current time base
value.
Sets the 9400A to 20 Bsec per division.
Sets the 9400A to I0 msec; since the value is
modified from 12 msec to I0 msec, the VALUE ADAPTED
bit in status byte 1 is set.
2) INTERLEAVED (IL) , <? >
< ON > *
< OFF > *
Enables or disables Interleaved Sampling.
The 9400A sets the ENVIRONMENT ERROR:
- if ON command is sent while the time base is greater than 2 US.
- if OFF command is sent while the time base is less than 50 NS.
3) TRIG DELAY (TRD) , < ?
< [ 0.00 % to i00.00 % ] >
<
[ -0.04 NS to -I000000 S ] >
Positive format:
Negative format:
pre-trigger.
post-trigger delay.
Valid
delay v~ues correspond to 0 to i0000 time base divisions in
steps of 1/50 of a division. If the TIME BASE is changed, the
delay remains the same or may change just slightly due to rounding,
provided that it does not exceed I0000 divisions.
Note:
In the case of post-trigger delay, the remote value is negative
while the corresponding value displayed on the screen is positive.
