Model 4200-SCS Reference Manual
Use the following command string to set these parameters:
PV A, BBB.BBBB, CCC.CCCC, DDD.DDDD, EEE.EEEE
PV
Pulse card channel
A = 1, 2, ... or n pulse card channel number. The largest permissible value of n equals the
number of channels in the system (8 maximum).
Pulse high in volts
BBB.BBBB
Pulse low in volts
CCC.CCCC
Pulse range in volts
DDD.DDDD
Current limit in amps (range and load dependent)
EEE.EEEE
Corresponding LPTLIB functions: pulse_vhigh, pulse_vlow, pulse_range,
pulse_current_limit
Example
For pulse card 1 channel 1, the following command string sets pulse high to +2V, pulse low to -2V,
pulse range to 5 V and current limit to 200 mA:
PV 1, 2, -2, 5, 200e-3
TO command: Set trigger output parameters
This command is used to set pulse delay and trigger polarity. The polarity setting affects both
channels of a pulse card. For example, setting channel 1 of pulse card 1 to positive trigger polarity
to also sets the trigger polarity of channel 2 to positive. For the trigger delay parameter, each
available channel can have its own unique delay setting.
Use the following command string to the pulse delay and trigger polarity:
TO A, BBB.BBBB, C
TO
Pulse card channel
A
