External Clock
Example: Selecting an external clock source and setting a clock divisor The
first command selects the external clock source on DAC channels 1 and
2. The external clock input is shared between these two channels. The
second command sets the clock divisor to 100 on the same DAC channels
(the external clock input signal is divided by 100).
SOURce:FUNCtion:CLOCk:SOURce EXTernal,(@1001,1002)
SOURce:FUNCtion:CLOCk:EXTernal:DIVisor 100,(@1001,1002)
Example: Outputting a clock The following commands set the clock output
frequency to 5 kHz and enable the output.
SOURce:MODule:CLOCK:FREQuency 5E+3,1
SOURce:MODule:CLOCK:STATE ON,1
External Trigger
Example: Selecting the external trigger source and issuing trigger source The
following command segment enables the trigger output mode and then
enables the external trigger source on DAC channels 1 and 2. The last
command issues an external trigger pulse from the module.
SOURce:MODule:TRIGger:OUTPut ON,1
SOURce:FUNCtion:TRIGger:SOURce EXTernal,(@1001,1002)
SOURce:MODule:TRIGger:EXTernal:IMMediate 1
Configuring a DAC Module
Example: Querying the system for module identify (all modules) The following
command returns the identity of the L4451A instrument.
SYSTem:CTYPe? 1
Example: Resetting the module(s) to power-on state The following command
resets the instrument.
SYST:CPON 1
Using this command will erase any downloaded waveforms.
