When a signal of 10 mV at 75 MHz is to be measured then which of the following instruments can be used –?
a.) VTVM
b.) Cathode ray oscilloscope
c.) Moving iron voltmeter
d.) Digital multimeter
none of the above!
You need a Spectrum Analyzer or a service monitor (Cushman CE3, CE5 etc)
me bad, I was reading facts not in evidence...
IF you are testing in circuit;
Yes, an o'scope wide enough to see 75MHz.
Yes, a VTVM with an RF probe
NO moving iron voltmeter
NO DMM
If you are testing remotely (as the FCC would from a monitoring station), then a spectrum analyzer.
