                                    INTRODUCTION
The Mobile Radio Test Set, TF 2950 has been designed as a
fully transistorised, multipurpose
unit capable of being driven from its own rechargeable
batteries. The main application
is for the testing, adjustment and servicing of mobile radio
communications equipment operating
in the VHF and UHF frequency bands.

1) An AM/FM signal generator covering the appropriate mobile
radio VHF and UHF
communications bands.
2) A modulation monitor for the measurement of amplitude
modulation depths up to 80% and
. peak frequency deviations up to +25 kHz.
3) An in-line power meter with a separate 15 W r . f . load.
4) An audio voltmeter having a sensitivity of 10 mV f. s . ,
an input impedance of 100 кй and
a bandwidth of 20 kHz.
5) An audio oscillator with a nominal frequency of 1 kHz
which is adjustable by up to +1% and
an output level variable up to 3 V.
5) An audio oscillator with a nominal frequency of 1 kHz
which is adjustable by up to +1% and
an output level variable up to 3 V .
