T - Command Trigger Mask
TYPE System Command
SYNTAX Tmask Set bit(s) in the Command Trigger Mask to specify which ports will be triggered by
the Trigger command ( @ ). The mask bits are as follows (bit values are shown in
parenthesis):
•
Bit 1 = Enable DAC port 1 to trigger on @ . (decimal 1)
•
Bit 2 = Enable DAC port 2 to trigger on @ . (decimal 2)
• Bit 3 = Enable DAC port 3 to trigger on @ . (decimal 4) (DAC488/4 only)
• Bit 4 = Enable DAC port 4 to trigger on @ . (decimal 8) (DAC488/4 only)
T-mask Clears the specified bits in the Command Trigger Mask.
T0 Clears all bits in the Command Trigger Mask.
T? Returns current Command Trigger Mask.
DESCRIPTION
The Command Trigger Mask enables or disables the specified DAC port for triggering by the Trigger command (@).
Note: The default bit value for each port is 0.
EXAMPLE
PRINT#1,"CLEAR09" Line 1: Reset the DAC488.
PRINT#1,"OUTPUT09;C1 T1 P1
A0 R2 V4 X"
Line 2: Select Indirect Control mode, enable port 1 to trigger on @,
select port 1, disable autoranging, select ± 5 volt range, output 4 volts.
PRINT#1,"OUTPUT09;@" Line 3: Trigger DAC port 2. The DAC488 will output 4 volts on port 1.
