Improving Accuracy with

While it is difficult to provide general advice for your speciEc measurement needs, the following suggestions may help you decide when to use the
1.Perform the frequency and amplitude
2.If the environment is relatively stable (for example, a lab environment), use CAL FREQ & AMPTD monthly. After being turned off overnight, the cable TV analyzer will need to warm up, but should not require
3.To achieve optimal amplitude accuracy for relative measurements:
a.Keep the cable TV analyzer in a stable environment.
b.Use CAL FREQ & AMPTD before beginning the Erst measurement.
c.Keep the cable TV analyzer turned on between measurements.
d. Do not use CAL FREQ 6 AMPTD before subsequent measurements (the amplitude drift is normally smaller than the
4.If you change the input signal for EXT REF IN, run the frequency and amplitude
5.If accurate
