STOP
Type:
Operational
Syntax:
STOP
Discussion:
The STOP command stops all measurements except
TEST and PROBECOMP. The STOP command is ignored
when TEST or PROBECOMP measurements are being
made.
When FALL, FREQUENCY, PERIOD, RATIO, RISE,
TIME, WIDTH, or EVENTS measurements are STOPped,
the measurement in process is aborted.
When TMANUAL or TOTALIZE measurements are
STOPped, the current result is retained and the measure-
ment can be restarted from the point where stopped.
STOP
TERMINATION
Type:
Setting
Syntax:
TER HI
TER LO
Examples:
TER HI
TERM LOW
TERMINATION HIGH
Query Syntax:
TER?
Query Response:
TER HI;
TER LO
-
Discussion:
The TERMINATION command sets the input termination
for the selected channel to the specified setting. Valid argu-
ments are:
HI
-
Set input termination to 1 MQ, 23 pF
LO
-
Set input termination to 50
Q
When the Termination setting is LO (50 Q) and an overly
large input signal (greater than 2 volts at XI attenuation) is
detected, the instrument automatically switches the Termi-
nation from LO to HI.
If the Termination is automatically switched from LO to
Hi, SRQ is asserted and remains asserted until the status is
read via a serial poll or until cleared by RQS OFF or device
clear. Channel A "50
Q
protect" is indicated by a Status
Byte of 102 or 11 8 and an ERROR query response of 602.
Channel B "50
Q
protect" is indicated by a Status Byte of
102 or 11 8 and an ERROR query response of 603.
The power-on initial setting is TERM HI.
For information on selecting channels, see the discussion
of the CHANNEL command.
