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 3 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
bandwidth. For rollkey 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 at the end of this chapter. For data entry, the
cursor keys ↑ and ↓ scroll through this list.
The manual input mode of the resolution bandwidth is indicated by a green
terisk (*) on the display.
IEC/IEEE-bus 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 rollkey 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 terisk (*)
on the display.
IEC/IEEE-bus command: BAND:VID:AUTO OFF;
BAND:VID 10 kHz
