Discussion:
The LEVEL command sets the trigger level of the pre-
viously selected channel to the value specified. The value is
expressed in volts and has a range of -2.000 to 2.000
when in x 1 attenuation and -10.000 to 10.000 when in
x 5 attenuation. The resolution is 0.004 for
x
1 attenuation
and 0.020 for x 5 attenuation.
The value is rounded to the nearest step and if this is not
within the range of the DC 5010 the trigger level is left un-
changed and an execution error (ERR 205) is issued.
For information on selecting Channels, see discussion of
the CHANNEL command.
LEVEL (TRIGGER LEVEL)
MAXIMUM
Type:
Query
Syntax:
MAX?
MAXIMUM?
Response:
MAX <number>;
Discussion:
The MAX? query returns a value indicating the maximum
input signal voltage for the selected channel measured dur-
ing the last autotrigger cycle. If the signal has changed
and/or the input signal conditioning has changed since the
last autotrigger, another AUTOTRIG is required to obtain
the new MAX 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).
