7 SPECIFICATIONS
7.4.2

Frequency Range and Channel Spacing

The T50, as a single model, covers the full band, and all channel spacing.
Frequency 25 kHz
25 - 50 MHz T50
7.4.3

Frequency Synthesizer Step Size

The specified frequency can be any multiple of 1250Hz.
7.4.4

Frequency Stability

± 5 ppm over 0 to +60 C, standard
± 2 ppm over -20 to +60 C, optional
7.4.5

Number of Channels

100, numbered 00 - 99
7.4.6 RF Output Impedance
50 Ω
7.4.7

Output power

The T50 needs an external PA50 power amplifier.
The output power is factory set to 100W by default, the reverse power level is set to
fold back the output power when the PA50 sees a load with VSWR of 3:1 or higher (i.e.
when the reverse power is 25% or more of the forward power).
7.4.8

Transmit Duty Cycle

100%
7.4.9

Spurious and Harmonics

Less than 0.25 µ W, when connected to a PA50 operating at an output power level of
100W.
