488.1 Protocol G-7
Command notes
SYSTem:TRIGger:CONTinuous <b> Applies to active channel
Trigger continuous mode was designed for use in conjunction with the 488.1 protocol
(SYST:MEP:STAT 0). When trigger continuous mode is enabled, the continuous trigger does
not cycle background readings, process commands that affect the measurement configuration
such as output state, function or integration time, etc., or service the other channel (if the
instrument has two channels).
On power up, this mode is set to disabled (OFF). This setting
is not saved in user setups.
While this mode is enabled, do not recall a user setup or send an *RST command.
Using trigger continuous mode
Trigger continuous mode provides a faster reading rate. The fastest reading rate is achieved
by enabling this mode along with enabling the 488.1 protocol (SYST:MEP:STAT 0). Also, the
format for readings can affect speed. Selecting SREal format will provide a faster reading rate
than when in ASCII mode. Enabling trigger continuous mode turns display OFF while disabling
it turns it back ON.
488.1 protocol and trigger continuous mode enabled
When the 488.1 protocol and trigger continuous mode are both enabled, talking the
instrument returns triggered readings. The query READ? does not have to be sent before talking
the instrument for a reading. When using this configuration (488.1 protocol and trigger
continuous mode enabled), the instrument is continuously taking triggered readings. When the
power supply is talked without being asked for data, a recently triggered reading is returned.
Changing instrument configuration
To change instrument configuration, disable trigger continuous mode first. Do not change
configuration while trigger continuous mode is enabled. After sending the commands to make
the desired changes, enable the trigger continuous mode and resume taking fast readings by just
talking the instrument.
