Q:
My V64xx powers-up with a static test pattern or black output, although a valid SDI video signal
is connected to one of its inputs.
A:
1. Check whether the Front Panel HD/SD LED is lit. This indicates that a signal is being received.
2. Check whether the Input selection is set correctly.

Q:
I want to add a number of frames extra delay to the output, but I cannot find the associated menu item.
A:
You need a V6402 (or a V6404/06/08/18SY) with the Field/Frame-Delay (FD) option enabled. This is a
factory installed option and requires a password in order to enable it. If the option is enabled, you will
find the corresponding control menu under
VIDEO
:
F Delay
.
Q:
The output generated by my V6406/08/18 looks corrupt.
A:
Make sure that the selected Output Standard has the same frame-rate as the Input signal.
Q:
I want to use my V6402 as a stand-alone Test Pattern Generator, but I cannot see anything on
the Monitor.
A:
1. Make sure that the selected 'Default Standard' is compatible with your Monitor specification
(
CONFIG
:
Def Std
). Note that some Broadcast Monitors cannot cope with progressively
scanned modes with frame-rates less than 50Hz.
2. Check whether the TPG is turned on an that you have not deliberately selected a 'Black' test
pattern (
