Every meter has a specified frequency range and it has
different frequency response (Nonlinear response)
A meter only responds to a portion of the RF spectrum.
Location is one of the most important factor impacts the RF
reading. If you have taken RF readings, you know that the
levels fluctuate widely from one moment to the next and from
one location to the next. Even moving the meter a few inches
to one side or another can have a large impact on reading.
14. Why the meter has different RF reading on different direction?
All RF signals have an orientation in space. They may be vertically or
horizontally polarized, they may be circularly polarized. The RF signal also
can be reflected by objects. The orientation of the meter’s antenna
direction to the signal will greatly impact the meter’s ability to detect the
signal. When multiple signals are present (with different orientations), it is
difficult to define the antenna orientation.
15. What is different between RF Standard mode and RF Sensitive mode?
The Standard mode on this meter is referring to average reading. Which is
the reading been calibrated to a RSM reading standard. The Sensitive mode
mostly reports RF pulse peak value. Most signals today are digital. Digital
signals are RF pulse signal (composed of a series of short bursts pulses). The
amplitude of pulses can differ by many times, sometimes more than 100
times.
