How to proceed:
For audio analysis, simply turn the volume knob of the speaker at
the top of the case all the way to the left (“-”). If you are switching to
audio analysis while high field strength levels prevail, high volumes
can be generated quite suddenly. This is especially true for meas-
urements which are to be taken without audio analysis. The knob is
not fastened with glue to prevent over winding. However, if by acci-
dent you should turn the knob too far, simply turn it back again. No
damage will be caused.
The volume can be controlled with the “audio” knob. Note: The
power consumption of the speaker is directly proportional to the
volume.
Use of Signal Outputs
AC output:
The AC output “PC/head-set”, 3.5 mm jack socket, is meant for in-
depth analysis of the AM/pulsed content of the signal by headset.
DC output
(2.5 mm jack socket) :
For a (longterm) recording of the display value. When “Full Scale” is
displayed, it has 1 VDC output.
The normal auto power off function is automatically deactivated as
soon as external devices are connected, and is only automatically
reactivated if a total discharge is imminent.

ƒ
HF-Analysers < 2,4 GHz
ƒ
Meters for the low frequencies: Also for this frequency range,
Gigahertz Solutions offers a broad range of professional meas-
urement technology. The new NFA series, for instance, which al-
lows a three-dimensional measurement of alternating electrical
and magnetic fields.
ƒ
Data loggers: All NFA-meters, starting from the NFA30M, can
equally be applied as data loggers for long-term recordings with
our HF analysers (only those with DC output).
