3.19.8 Peak Power Sensor Commands
Commands related to the peak power sensor are based on the function code PEAK. (For the sake of
backward compatibility with earlier Giga-tronics power meter designs, the command PULSE is accepted
as a substitute for PEAK).
Series 80350A Sensors SENS
The command format for setting trigger modes and levels is:
Syntax : PEAK [A or B] [INT or EXT] TRIG [n]
A or B specifies Sensor A or Sensor B.
[INT or EXT] specifies internal or external triggering.
TRIG indicates that a trigger level is being set.
[n] specifies the trigger level in units of dBm in the case of internal triggering, or volts in the
case of external triggering.
Examples : OUTPUT 713:PEAK A INT TRIG -10.00 ! Configure sensor A for internal triggering at
! a trigger level of -10.00 dBm
OUTPUT 713:PEAK B EXT TRIG 1.50 ! Configure sensor B for external triggering
! at a trigger level of 1.50 Vdc
The command format for selecting the CW mode is:
Syntax : PEAK [A or B] CW
[A or B] specifies Sensor A or Sensor B.
CW specifies the CW mode.
Example : OUTPUT 713:PEAK A CW ! Configure sensor A for CW measurements
A delay between the trigger and the actual measurement can be specified (in the CW mode, delay
settings have no effect). The command format for setting the delay is:
Syntax : PEAK [A or B] DELAY [n]
[A or B] specifies Sensor A or Sensor B.
DELAY indicates that a delay value is being set.
[n] is a numerical variable which specifies the delay in seconds. It has a range of -20E-9
(-20 ns) to 104E-3 (104 ms).
Examples : OUTPUT 713;PEAK A DELAY 1.20E-6 ! Configure sensor A for a delay of 120
µ
s
OUTPUT 713;PEAK B DELAY 33.5E-9 ! Configure sensor B for a delay of 33.5 ns
NOTE:
The actual duration of the delay is the sum of this setting and the delay offset setting.
