Performance Check
RFM 150 Instruction Manual 5–3
Required Equipment
RF Signal Source
Frequency Range: 10 MHz to 1000 MHz
Accuracy:
±
500 Hz
Amplitude Range: 0 dBm maximum output (50
W
or 75
W
)
FM Modulation (internal or external): Deviation range 5 kHz to
25 kHz. Rate between 20 Hz and 7.5 kHz.
AM Modulation (internal or external): Amplitude range 0 to 2.5%
(corresponds to 0 to 5% RFM 150 reading). Rate 50, 60, 100 or
120 Hz.
Example: Hewlett-Packard 8657A Signal Generator with a Tektronix
CFG250 Function Generator
The function generator is used when testing hum accuracy, to drive
the external modulation input to generate the 50, 60, 100, or 120 Hz
AM modulation rate.
Function Generator
For testing hum accuracy, use a function generator to drive the
external modulation input of the RF signal source to generate a
60 Hz sine wave.
