order to prevent possible measuring errors due to insufficient
transient response time.
(17) 5dB/Div.
Py pushing the 5 dB/Div. button, the vertical scale is set to 5 dB/
Div. The respective LED will then be lit. To enter again in 10 dB/
Div. mode, push 5 dB/Div. again.
(18) RBW (Resolution Bandwidth):
The instrument is equipped with resolution filters of 9kHz, 120kHz,
and 400kHz, which can be selected via the „RBW" buttons. The
respective LED will indicate which bandwidth is selected.
Remark:
A maximum measuring bandwidth and the Max.HLD function
should be selected for pulsed signals.
(19) VBW-Video Filter:
The Video Filter has the purpose of reducing video and noise
bandwidth and therefore reducing noise distribution. When
measuring low level values, which are situated within the regular
noise level, the Video Filter (low pass) can be used to reduce the
noise level. This allows for the detection of even small signals
which might otherwise not be visible.
Remarks:
Please note that if frequency range (SPAN) is too high and Video
Filter is active, amplitude readings might be wrong (too small)
