PANEL DESCRIPTIONS
Front / Rear Panel
1. SDI Input: Plug in a SDI cable to be linked to a SDI source
2. LCD Display: the measured data is shown here
3. Push Button: Turn on the device and view the device data
4. Battery Holder: Place an alkaline 9 volt “transistor” battery here
HARDWARE INSTALLATION
1. Disconnect the coaxial cable from the receiving terminal.
2. Connect the coaxial cable to the “SDI Input” BNC connecter on the AV-GM0913-S1.
3. Push the “ON” button of the AV-GM0913-S1 to turn on the device and see the device data.

INSTRUCTION
1. AV-GM0913-S1 has a power on timer to allow enough time to do the measurements and then
turn off the device to save the battery. The AV-GM0913-S1 will show “Power Down” on the LCD
display before the device turns off. The AV-GM0913-S1 will keep operating for another period if
the user pushes on the button during this time. The LCD display will flash one time when the
AV-GM0913-S1 do another battery check.
2. The AV-GM0913-S1 also has a LCD back lighting feature. This feature can light the device in the
dark environment. The LCD display will keep lighting if user hold on the button. The light will
stop when user release the button. If not needed, user should avoid to this function because this
function will use much battery power.
3. The data is in dBm on the left side screen. The standard dBm data(full level signal) is 0. If the
signal is larger than 0, the dBm data will be a positive number. On the other hand, if the signal is
loss or lower level than 0, the dBm data will be a negative number.
4. The data is in millivolts peak-to-peak on the right side screen. The millivolt data is showed as a
reference and moves in one db steps. The millivolt peak to peak data uses a floating decimal
point to improve the readout. Besides, the data of 0.800 volts peak-to-peak means that the direct
nominal output of a digital video source is measured.
5. Because the HD signal is transmitted over the coaxial cable, the voltage will be decreased with
increasing distance.
6. The Belden 1694A Precision Video Cable is commonly used by the Television Broadcast Industry.
Using this cable, the signal strength of the highest frequency of interest in HD is expected to
drop 84.9% for each 100 meters of cable. However, the actual signal strength is expected at
various lengths of cable is shown in the below table.

7. The data generator’s strength is supposed to be 800 millivolts at the output, but it may vary as
much as +/- 10% from this value. So user can expect that the AV-GM0913-S1 reading may vary as
least that much when estimating the cable length using the signal strength that is measured.
Therefore, for greater accuracy you can measure the source level, record that number and
subtract that number from the end of line measurement to get an exact measure of the loss of
the cable.

NOTICE
1. If user wants to use an SDI camera as a source signal, it is recommended that user uses a high
pass filter in line ahead of the device.
2. The AV-GM0913-S1 is an exactness measuring device. Although it can endure normal everyday
indoor use, it could not be left outside in the rain or mistreated. It does not have waterproof
function.

3. In order to prevent leakage of corrosive fluids from battery, the battery should be removed when
AV-GM0913-S1 is placed into storage.
4. Please replaced non-rechargeable batteries at least once a year to prevent the old battery
causing the leak and corrosion damage.
