First measurement
These examples also include a table to demonstrate how to
achieve a sufficiently exact measurement even with unknown
frequencies.
Of course, broadband measurements have their limitations
when evaluating the actual emitted signal strength, particularly
in the context of modern digital signals. Thus these instructions
should be considered with care.
Nonetheless, it’s still a nice technical tool for a „quick
assessment“.
To detect a signal maximum, you should definitely use the Hold
function (see chapter 8.6) and the so-called „panning
approach“ (see chapter 8.7). We recommend this suggestion
for this mode in particular, due to the extremely fast display
updates. This is the only way to accomplish a useful
“measurement”.
Still, the intended application for the broadband option is
operation as a power meter. Its high temperature stability
guarantees highly reproducible results. The instrument’s input
impedance is “standard” 50 Ohms, so a broad range of
equipment and antennas can be connected without any
troubles. The highest accurady is reached with attenuator =
10dB and PreAmp = Off. Don’t forget the maximum levels in
this configuration.
Attention: Take care not to overload the input.
Tip
: You can upgrade your instrument with the broadband option at any time. Depending on
your model, detectors for up to 10GHz (12GHz) are available.
Tip
: If the broadband detector is installed, the bargraph can also be activated (use the
BackBB function) to always show the peak signal strength measured by the detector. Even in
spectrum analysis mode, where normally the frequency selective measurement result is
displayed, the bargraph will then always show the broadband peak power measured by the
broadband detector.
