Attenuator repeatability
Mechanical attenuator
typically 0.1 dB
RF output connector:
Front panel 50 Ω, type N female connector to MIL-PRF-39012 Class 2
Output protection:
Protects the instrument from externally applied RF power (from a 50 Ω source) of 50 W
up to 3 GHz or 25 W up to 4 GHz.
The RPP trip can be reset from the front panel or via the remote interface. For safety,
protection is also provided when the instrument is switched off.
3416 damage level 0.5 W (+27 dBm) from a max 5:1 VSWR, all frequencies.
