3.5 Performing Synchronized Measurement with Multiple Instruments
78
You can perform synchronized measurement by connecting multiple (up to eight: one master and up to seven
slaves) instruments (PW3335) with optional 9165 Connection Cord (BNC cable).
This functionality can be used to perform simultaneous measurement of multiple circuits by operating only the
instrument (PW3335) set up as the master (instrument setting of OUT) and thereby controlling the instrument
(PW3335) set up as the slave (instrument setting of IN).
The instrument (PW3335) set up as the slave will match the timing of the instrument (PW3335) set up as the
master for the following operations:
• Internal calculations
• Display updates
• Data updates
• Integration start, stop, and reset
• Display hold
• Zero-adjustment
•Key lock
The PW3335 can also be used with the PW3336 and PW3337 series of power meters to perform synchro-
nized measurement.
3.5 Performing Synchronized Measurement with
Multiple Instruments
(Multiple-instrument Synchronized Measurement)
• To avoid damaging the instruments, do not connect or disconnect cables while the instru-
ments are turned on.
• In synchronized measurement, do not input any signal other than those specifically sup-
ported by the instrument’s synchronized measurement function. Doing so may result in mal-
function or damage.
• Use a common ground for instruments (PW3335) that are performing simultaneous mea-
surement. If different grounding is used, a potential difference will occur between the master
ground and the slave ground. Connecting the connection cable (for synchronization) while
there is such a difference may result in malfunction or damage.
