The
…BW MANUAL
softkeys allow a parameter to be entered. This parameter is not
coupled to the other parameters.
RES BW
MANUAL
The
RES BW MANUAL
softkey activates the manual data entry for the resolution
bandwidth.
The resolution bandwidth can be selected in 1/3/10 steps in the range between 10
Hz and 10 MHz. The nominal resolution bandwidth is the 3 dB bandwidth.
When FFT filters are used, the lower limit of the bandwidth is 1 Hz. FFT filters may
be used with bandwidths up to 30 kHz.
For numeric inputs, the values are always rounded to the nearest possible band-
width. For rotary knob or UP/DOWN key inputs, the bandwidth is adjusted in steps
either upwards or downwards.
For filter type CHANNEL or RRC, the bandwidth is selected from the list of available
channel filters given in section
For data entry, the cursor keys
U
u
and
U
d
scroll through this list.
The manual input mode of the resolution bandwidth is indicated by a green asterisk
(*) on the display.
Remote command:
BAND:AUTO OFF;
BAND 1MHz
VIDEO BW
MANUAL
The
VIDEO BW MANUAL
softkey activates the manual data entry for the video
bandwidth.
The video bandwidth can be selected in 1/3/10 steps in the range between 1 Hz and
10 MHz.
For numeric inputs, the values are always rounded to the nearest possible allowed
bandwidth. For rotary knob or UP/DOWN key inputs, the bandwidth is adjusted in
steps either downwards or upwards.
The manual input mode of the video bandwidth is indicated by a green asterisk (*)
on the display.
Remote command:
BAND:VID:AUTO OFF;
BAND:VID 10 kHz
SWEEPTIME
MANUAL
The
SWEEPTIME MANUAL
softkey activates the manual data entry for the sweep
time. At the same time, the coupling of the sweep time is cancelled. Other couplings
(
VIDEO BW, RES BW
) remain effective.
In the frequency domain (span > 0 Hz) and for resolution bandwidths above 1 kHz,
the allowed sweep times for spans > 3.2 kHz range from 2.5 ms through to 16000 s.
With spans below 3.2 kHz, the maximum allowed sweep time is reduced to 5 s *
span/Hz.
If FFT filters are used, the sweep time is fixed by the span and the bandwidth and
therefore cannot be set.
With the
…BW AUTO
softkeys the resolution bandwidth, the video bandwidth and
the sweep time can be entered separately for the frequency domain (span > 0 Hz)
and the time domain (span = 0 Hz).
But with
…BW MANUAL
softkeys the selected values apply to both the frequency
and time domain.
