MINIMUM
Type:
Query
Syntax:
MIN?
Response:
MIN <number>
Discussion:
The MINIMUM? query returns a value indicating the mini-
mum input signal voltage for the selected channel measured
during the last autotrigger cycle. If the signal has changed
and/or the signal conditioning has changed since the last
autotrigger, another AUTOTRIG is required to obtain the
new MIN values.
An autotrigger cycle occurs for each AUTOTRIG,
PROBECOMP, RISE, or FALL operation. The maximum ex-
ecution time for each operation is 2.5 sec, (1.5 sec, typical).

/ - \
The NULL command controls the storing of measure-
ment results to be subtracted from all subseql~ent measure-
ments. Valid arguments are:
ON
-
Store current measurement result and subtract it
from all following measurements.
OFF
-
Reset stored Null value.
The Null value is reset each time the NULL OFF com-
mand is executed and each time a FUNCTION COMMAND
IS EXECUTED. For Time interval measurement (TIME,
WIDTH, RISE, FALL) the Null value is reset to 5.2 nsec to
provide compensation for propagation delay time between
Channels A and B input circuitry. For all other measure-
ments, the Null value is reset to 0.
The power-on initial setting is NULL OFF.
