Monitor (C/A)
This unit receives the composite color video signal
from the VMU tuner and shows color pictures. The
input impedance must be 75 W (±1%).
NOTE: If you use your RF video receiving equipment
for VMU testing (Toshiba TT-GC9 or TT-GC10 TV
tuner, video cassette recorder, etc.), the
monitor must be the one that is connected to
your receiving equipment.
T&FI-2
Oscilloscope (C/A) DC to 40 MHz, precision of ±3% for 1 Vp-p video
signal measurements.
T&FI-2
RF Cable (C/A) BNC-BNC 50-W coaxial cable. Three sets are
necessary (RFC1 thru RFC3).
T&FI-2
Video Cable (C/A) BNC-BNC coaxial cable. Four sets are necessary
(VC1 thru VC4). The cable impedance can be 50 or
75 W.
T&FI-2
BNC Tee Adapter
(C/A)
Two sets are necessary (T1 and T2). T&FI-2
Monitor Cable (C/A) One set is necessary to connect the output (BNC) of
the VMU tuner to the input of the video monitor.

Ceramic Alignment
Screwdriver or
Flat-Blade
Screwdriver (C/A)
Use this to turn VR100, VR101, VR200 and VR201
(variable resistors) on the A1 card and VR301 on A4
card. We recommend to use a ceramic alignment
screwdriver (all insulating material) to prevent
accidental damage to the A1 and A4 cards.
T&FI-2
Volt-Ohm-
Milliammeter (VOM)
or Digital
Multimeter (DMM)
(C/A)
Use a VOM or DMM for continuity check and fault
isolation. It must be an "ISOLATED" type, such as
a battery-operated one, for fault isolation on the
primary circuits of the A5 card.
