Description

 

 

Power

This instrument is intended to operate from a single-phase power source with one current-carrying

 

conductor at or near earth ground (the neutral conductor). Only the Line conductor is fused for

 

over-current protection. The fuse is internal, on the Power circuit board. Systems that have both

 

current-carrying conductors live with respect to ground (such as phase-to-phase in multiphase systems)

 

are not recommended as power sources. Mains frequency is 50 or 60 Hz. Operating voltage range is

 

continuous from 100 to 240 VAC, ±10%.

 

 

Video inputs

The waveform monitor provides the following video input connectors:

 

NOTE: Input A and Input B are separate signal inputs and cannot be used as a loop-through signal path.

 

INPUT A and INPUT B. Digital, 75 Ω terminating input for signal to be monitored. For WFM700HD, this

 

can only accept 1.485 Gb/s High Definition serial video. For the WFM700A and WFM700M, this input can

 

accept HD and 270 Mb/s Standard Definition video.

 

REF IN LOOP-THROUGH. Compensated for 75 Ω impedance; requires proper termination at one end of

 

the loop-through connector or at the receiver in a monitored system. Provides for connection of an

 

external synchronization signal such as black burst or composite video.

 

AUX IN. Future capability.

 

 

Audio inputs / outputs

When your instrument has the optional WFM7DG audio module installed, the waveform monitor provides

(Option DG only)

BNC connectors that function either as inputs for external AES/EBU audio (not necessarily associated

 

with any video) or as outputs of the de-embedded AES audio associated with the selected video input.

 

Use the Audio Inputs/Outputs submenu of the Configure menu to configure these connectors.
