Expression Details
aux_line_mnemonic Define the output of the auxiliary line.The possible values are NONE, ON, OFF, OVOLtage, UVOLtage,
OCURrent, UCURrent, OPOWer, UPOWer, ACOFf, OTEMperature, HTEMpertature, SPRotection,
UNRegulated, FOLD, CC, CV, CP.
channel The address for a multichannel slave. An integer value in the range 2 to 50.
codeword A string representing any 4-digit positive integer.
current A numeric value as defined by SCPI. May also be MAXimum or MINimum. May include current-related
suffix units such as “mA”, “uA”, “A” etc. Range may be 0 to 103% of model’s rated current.
delay A length of time in the range 0 to 60 seconds. May include time-related suffix units such as “S”, “MIN”,
“mS”, “uS” etc. By default, the value is in seconds.
ESE-word Range 0–255. An 8-bit status mask for the Standard Event Status Register that determines which bits are
OR’d to form the ESB bit in the Status Byte Register.
GPIB_address The address for a GPIB controlled unit. An integer value in the range 1 to 30.
on-off-state A Boolean indicator of a state. Possible values are ON, OFF, 0 (off), or 1 (on).
OVP_level A numeric value as defined by SCPI. May also be MAXimum or MINimum. May include voltage-related
suffix units such as “mV”, “uV”, “V”, etc. Range is 0 to 103% of model’s rated voltage.
power A numeric value as defined by SCPI. May also be MAXimum or MINimum. May include power-related
suffix units such as “mW”, “uW”, “W”, etc. Range is 0 to 101% of model’s rated power.
setting_location A numeric indication of an internal set of setting registers. An integer value in the range 1 to 10.
sequence_count Number of times a sequence is to be repeated. Range is 1 to 9999.
sequence_number The name of an auto sequence program. Range is 1 to 10. The suffix is part of the SEQUENCE command
name and is not a parameter.
status-enable A 16-bit status mask for any condition register that determines which bits are to be used for synthesizing
the summary bit of that register.
step_number The step number of an auto sequence program. Possibly considered a SCPI suffix. Range is 1 to 99.
step_time The duration of an auto sequence step in the format hh:mm:ss.s.
May include time-related suffix units such as “S”, “MIN”, “mS”, “uS”, etc. By default, the value is in
seconds.
voltage A numeric value as defined by SCPI. May also be MAXimum or MINimum. May include voltage-related
suffix units such as “mV”, “uV”, “V”, etc. Range is 0 to 103% of model’s rated voltage.
