Specifications

SETTling[:TIME] [ROUTe:]SETTling[:TIME] <time> , <channel_list> sets the delay
between the multiplexer’s receipt of a trigger command, and the generation
of the "channel closed" pulse. The
SETTling[:TIME] command applies to the
FET (strain gage) multiplexers only. You must specify one and only one
channel for each multiplexer in the switchbox instrument. The time applies
to all channels on the multiplexer. The range is 1 µsec to 32.768 µsec.

Parameter Name Parameter Type Range of Values
time
Numeric 1E-6 | 32.768E-3 | MIN | MAX
channel_list
Numeric only one channel
Comments • Using an External Voltmeter: When using an external voltmeter
with the FET strain gage multiplexer switchbox, a "voltmeter
complete" signal is often used to trigger the multiplexer to close a
channel. Because of the speed at which a FET channel closes, the
channel closed pulse often occurs before the multimeter is ready to
make the measurement. The
SETTling:TIME command delays the
channel closed pulse until the voltmeter is ready.
• Digital Bus Handshaking: Operation of the digital bus is described
in the HP E1326B/E1411B Multimeter User’s Manual.
• Related Commands: TRIGger:SOUR DBUS, TRIGger:SOURce IMM
Example Setting the Maximum Settling Time
TRIG:SOUR DBUS Selects external trigger source.
SCAN:MODE VOLT Selects the voltage scanning mode.
SCAN:PORT ABUS Selects the ABUS port.
SETT:TIM MAX,(@100) Sets the maximum channel closed
pulse delay.
SCAN (@100:107) Sets channel list.
INIT Starts scanning cycle.
SETTling:TIME? [ROUTe:]SETTling:TIME? [MIN | MAX] , <channel_list> returns the
current setting for a specified channel.
MIN or MAX returns the minimum
and maximum allowable settings.
