Signal Inputs
SyncVu™
The SyncVu™ feature works with the simultaneous input monitoring (SIM) mode
and allows you to configure the settings for two inputs at the same time. To set the
instrument t
o SyncVu™ mode after you are in SIM mode, do the following:
1. Press the MAIN button.
2. Select SyncVu.

How t o Change Settings
Using SyncVu
This instrument can d isplay four tiles. When you are viewing two inputs
simultaneously in SIM mode, the tiles on the left side of the display show the first
input. The tiles on the right side of the display show the second input. The display
type in tile 1 for the first input is the same display type shown for the second input
in tile 2: Top left to top right and bottom left to bottom right. SyncVu™ allows
you to c
hange the settings for the two related tiles at the same time.
For example, if you have a waveform display in tile 1 of input 1A, then tile 2 is
the wa
veform display for the second input. When you adjust the settings for the
waveform displayed in tile 1, the settings for the waveform displayed in tile 2 are
adjusted simultaneously. Similarly, adjusting settings for tile 2 are applied to tile 1.
Reference Loop
Reference signals can be Black Burst or Tri-level sync. After you connect the
appropriate reference signal, press the EXT REF button the on the front panel
of the instrument. You can also choose whichformattolocktobypressingthe
CONFIG button and selecting External Ref. The default setting is Auto.
The reference input is passive and requires external termination. If you install
this instrument to monitor an operating link, the destination receiver and the
c
onnecting cable serve as the termination. This monitoring connection checks the
performance of the entire path. The return loss of the instrument is sufficiently
high that, in most cases, the destination receiver sets the system return loss.
