TEST EQUIPMENT REQUIRED
A certain amount of quality test equipment is necessary to service to-
day' s sophisticated communications ea.uipment. Below is a list of that re-
quired for the ASTRO l02BX.

capable of ~200W dissipation
-Light bulb load, 100W, 10 ohms cold
-oscilloscope, 30 MHz minimum band-
width, with xlO attenuator probe
to be used for all measurements
-Frequency counter, at least 100 mV
sensitivity, high impedance in-
put, counts to
44
MHz or higher
-VTVM or DVM with high input im-
pedance to be used for all AC and
W
measurements
