[
SENSe<1|2>:]BANDwidth|BWIDth:VIDeo:RATio
This command defines the ratio video bandwidth (Hz) / resolution bandwidth (Hz).The ratio to be
entered is reciprocal to the ratio RBW/VBW used in manual operation.
The numeric suffixes <1|2> are not relevant.
Parameter
0.01 to 1000
Example
BAND:VID:RAT 3
Sets the coupling of video bandwidth to video bandwidth = 3*resolution bandwidth
Characteristics
*RST value: 3
SCPI: conform
Mode
A, EVDO
[SENSe<1|2>:]BANDwidth|BWIDth:VIDeo:TYPE
This command selects the position of the video filter in the signal path, provided that the
resolution bandwidth is 100 kHz.
The essential difference between the two modes is the transient response at falling signal
edges: If LINear is selected, the measurement with logarithmic level scaling yields a much
"flatter" falling edge than LOGarithmic. This behavior is due to the conversion of linear power
into logarithmic level. If the linear power is halved, the level decreases by only 3 dB.
The numeric suffixes <1|2> are not relevant.
Parameter
LINear The video filter is connected ahead of the logarithmic amplifier (default).
LOGarithmic The video filter follows the logarithmic amplifier
Example
BAND:VID:TYPE LIN
Video filter ahead of the logarithmic amplifier
Characteristics
RST value: LIN
SCPI: device–specific
Mode
A, CDMA, EVDO
