Option SD/HD Procedure
Determine the AWVG7
Signal Output Amplitude
This procedure determines the test signal generator output signal amplitude. You
will need this value for calculating measurements. This procedure assumes you
are using a Tektronix TG700 test signal generator with an AWVG7 module. If
you are using a different test signal source, modify the steps according to your
particular setup.
Required
equipment
HD CAV Television Test Signal generator (Tektronix TG700 with
AWVG7 module)
Digital multimeter
75 Ω BNC Cable (1)
75 Ω precision BNC terminations (1)
Connector, Dual-Banana (1)
Connector, BNC ‘T’ (1)
Prerequisites
The test signal generator and multimeter must warm up for at least 20
minutes before doing this test.
NOTE. Make sure that the AWVG7 generator module and the multimeter have
had a warm up period of at least 20 minutes.
1. Connect the digital multimeter to the test signal source. Refer to Figure B--1
while doing the following steps:
a. Connect one end of a 75 Ω BNC cable to the upper CH1 connector on
the AWVG7 generator module.
