OPERATING INFORMATION
TR PCC {x} Trigger Control, where the secondary PCC is one of the following:
ED {v} External Drive (threshold set for v volts)
EP External Trigger Slope, positive
EN External Trigger Slope, negative
ET {v} External Trigger {threshold set for v volts}
IN {f} Internal Trigger {rep rate set to f Hertz}
SC Single Cycle
If the value {x} is omitted, the current value is returned. If the string TR IN 1E3 were sent,
the internal rep-rate generator would be set for a frequency of 1.000 kHz. A subsequent
string
TR IN would cause the return of the 20 character string Trg Int: 1.000 kHz."
Once Single Cycle operation has been selected, the 6040 can be triggered with the EX
command (see the Supplemental Control Commands section).
TI PCC {x}
Timing Control, where the secondary PCC is one of the following:
DL {t} Delay {set for t seconds}
WD {t}
Width {set for t seconds)
SP Single Pulse
DP Double Pulse
Width and Delay commands terminate the current liming cycle when received by the
6040 (just as the EXEC key does under manual operation).
If the value {x} is omitted, the current value is returned. If the siring TI WD 1.23E-3 were
sent, the delay would be set for 1.2300 ms. A subsequent string TI DL would cause the
return of the 20 character siring "Width 1.2300 ms."
LV PCC {x}
Level Control, where the secondary PCC is one of the following:
AV {x} CW level {set for x units}
BL {x} Baseline level {set for x units)
EM {x} External Modulation level {set for x units)
PK {x} Peak level {set for x units}
If the value (x) is omitted, ihe currenl value is relumed. If ihe siring LV PK 1.23E-3 were
sent, the peak level would be set to 1.23 mW (for an optical module). A subsequent
siring
LV PK would cause the return of the 20 character string "Lv Peak: 1.23 mW."
The unit used is dependent on the module.
