“Rattling tone” for marking of un-pulsed
transmitters
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.

UBB27 is a perfect match to the Fre-
quency Filter FF6E

the most important radio services.

Limits for using the variable frequency
filters VF2 and VF4
filters VF2 and VF4
When set to “bypass” the variable fre-
quency filters VF2 and Vf4 have a high pass
frequency band curve which begins to at-
tenuate frequencies below a couple of 100
MHz. The analysis in the band of 27 to sev-
eral 100 MHz therefore are to be done
without VF2 or VF4 mounted to the instru-
ment.

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.

Below 85 MHz the tolerance level of the
setup for the calibration becomes predomi-

the demonstration of the instrument. A simu-

lower limit, proves a very good linearity down
to 27 MHz. Without verification we cannot
