DELAY? Tx
Form:
Set & Query
Description:
Delay time of channel Tx relative to channel Ti (reference channel)
is set to delaytime picosecond
Parameter:
Tn: channel number 1 to 4 (or 1 to 8 for 8 channel)
Ti: channel number 0 to 4 (or 0 to 8 for 8 channel)
Tn and Ti have to be different
delaytime: picosecond delay
RST value
-
Specified limit
0 to 19 999 999 999 999 picoseconds
Example:
Set : program 1ns to channel 2 relative to channel 1 : DELAY T2, T1,
1000.75
Query: DELAY? T2 => :DELAY T2, T1, 1000.75
Note : By using the Web page or Telnet command to configure the
device, user can specify delay with 0.25ps resolution.
ABSOLUTE DELAY
Syntax:
ABSDELAY? Tx
Form:
Query
Description:

-
Example:
Query: ABSDELAY? T2 => :DELAY T2, 5000.75
TRIG
Syntax:
TRIG Tx,DEC
TRIG? Tx
Form:
Set & Query
Description:
Tx trigger mode selection: set trigger mode to internal, external,
manual or off.
Parameter:
Tx: channel number 1 to 4 (or 1 to 8 for 8 channel)
DEC: trigger mode : IN1, IN2, EXT, SS1, SS2, SSE, LSS, BST, OFF
RST value
off
Example:
Internal mode to channel 2 : TRIG T2,IN1
Query mode to channel 2: TRIG? T2 => :TRIG T2,IN1
AMPLITUDE
Syntax:
AMPL Tx, mV
