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).
3.19.8.1 Series 80350A Peak Sensors
The command format for setting trigger modes and levels is:
Syntax: PEAK [A or B] [INT or EXT] TRIG [ n ]
PEAK the function code related to the peak power sensor
[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
Example:
PEAK A INT TRIG -10.00 ! CONFIGURES PEAK SENSOR A FOR INTERNAL TRIGGERING AT
! A TRIGGER LEVEL OF -10.00 DBM
Example 2:
PEAK B EXT TRIG 1.50 ! CONFIGURES PEAK 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
PEAK the function code related to the peak power sensor
[A or B] specifies Sensor A or Sensor B
CW specifies CW mode
Example:
PEAK A CW ! CONFIGURES PEAK 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 ]
PEAK the function code related to the peak power sensor
[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 -50.5E-9 (-50.5
ns) to 104.8E-3 (104.8 ms)
Example:
PEAK A DELAY 1.20E-6
! CONFIGURES PEAK SENSOR A FOR A DELAY OF 1.20
µ
S
Example 2:
PEAK B DELAY 33.5E-9 ! CONFIGURES PEAK 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.
