significant to note which technique was used
for each measurement.
"Rattling tone" for marking of un-pulsed
transmitters
When using the HF59B in audio analysis
mode with the UBB27 attached (The switch
"Signalanteil" or "Signal" set to "Voll" or
"Full"), one will almost always hear a rat-
tling tone. This is because sources of un-
pulsed radiation are almost always present
in the very broad frequency range of the
UBB27. The loudness of it is proportionate
to the percentage of un-pulsed radiation in
the total signal received. The marking is
done with a frequency of 16 Hz (very low).
An audio sample can be down-loaded as a
MP3 file from our home page.
Limits for using the RF amplifier HV10
Only the HF59B can supply enough Power
for the UBB27 plus the HV10. The battery
life decreases by ~20%.
The external attenuator DG20_G3, may be
used with the UBB27 plus either HFE35C
or HF59B.

Accuracy
By itself, the UBB27 inaccuracy range of +/-
3 dB extends from approx. 85 MHz up to 3.3
GHz. The antenna continues to work beyond
that, but with increasing attenuation.
We state the total accuracy of our HF analyz-
ers for the complete assembly of analyzer
plus antenna in a far field under well defined
conditions. (An "average measurement" with
the complete assembly placed on a non-
conductive support). The measurement inac-
curacies for the complete assembly are the
following:
HFE35C plus UBB27 stays the same, and
HF59B plus UBB27 increases moderately
to +/- 4.5 dB.
Below 85 MHz the tolerance level of the set-
up for the calibration becomes predominant
and limits the accuracy achievable for the
demonstration of the instrument. A simula-
tion, which demonstrated an excellent corre-
lation of actual measurement and simulated
signals in the frequency band above the low-
er limit, proves a very good linearity down to
27 MHz. Without verification we cannot guar-
antee the accuracy. Frequencies below 27
MHz are damped out by an internal, extreme-
ly steep high pass filter.
NOTE: The UBB27 causes a noise of up to 5
µW/m² in the "Min" range. With the HF59B
this can be reduced significantly by using the
"Full" mode.
