What instrument is used to tune an low power UHF rf receiver used for general purposes?
1) What instrument is used to tune an low power UHF RF receiver used for general purposes?
2) Where can I purchase this instrument?
3) Do these kind of instruments normally come with an option to check the frequency of oscillation using physical contact via probes or an antenna?
Any help in the right direction will be much appreciated.
“A low power”, please!
Receivers have sensitivity, not power, except in the audio or output stage(s).
The better the sensitivity, the better the chances of detecting a weak signal.
Instruments for tuning may range from a simple multimeter to specialist RF test sets. Only multimeters are cheap.
In a receiver, the only frequencies of oscillation are those of the local oscillator(s). These are generally checked using a frequency counter directly connected.
If you are talking about reading a received frequency, these are generally read by measuring the 1st. local oscillator frequency, and allowing for its offset from the receive frequency in question.
A UHF receiver will usually have 2 local oscillators and intermediate frequencies.
