Functional Check and Installation
It is good practice to perform a functional check of a new instrument before
installing it into your system.
Perform the following functional check to confirm proper operation of your new
VITS inserter and to familiarize yourself with its features.
1. Unpack the instrument. If possible, save all packing materials for later
shipping or storage.
2. Connect the VITS inserter to the local AC power supply with the cord
provided with the instrument. The VITS inserter operates on any 48–62 Hz,
90–250 V supply; no switch or jumper settings are required.
3. Connect the VITS inserter to a test signal generator and waveform monitor
as shown in Figure 1–1.
4. Switch only the VITS inserter on. Confirm that, after approximately one
second, all three front panel LEDs are lit.

5. Switch the test signal generator on and configure it, if necessary, to output a
signal that does not contain any VITS (if it is available, select Black Burst).
Confirm that the VITS inserter BYPASS and UNLOCKED LEDs are no
longer lit.
6. Switch the waveform monitor on and configure it to display two fields of the
VITS inserter PROGRAM OUT waveform.
