VSWR (typical)
Note 1: BNC with Probe Read Out Pin which causes the instrument to change V/div indication,
input impedance and attenuator setting according to probe (when fitted with a probe
indicator).
Note 2: Measured up to 200 MHz input frequency; in d.c. and a.c. coupling of input.

Coupling

COUPLING
Note 1: In GND position: channel disconnected from input, and connected to ground, BNC open
(when not in 50Q. position). The GND coupling is not available for CH3 and CH4 in
PM3092 and PM3082.
