Level Display And Rf Input Configuration - Ampt Key - R&S ESU Series Operating Manual

R&S ESU
IF RBW The IF RBW softkey activates the manual entry mode for the resolution bandwidth.
For filter type NORMAL (3dB), the bandwidth can be set from 10 Hz to 10 MHz in
steps of 1/3/10. For filter type NORMAL (6dB), the 6-dB bandwidth 200 Hz, 9 kHz,
120 kHz and 1 MHz can be set.
For numerical inputs, the values are always rounded to the next valid bandwidth. For
rotary knob or the UP/DOWN key entries, the bandwidth is adjusted in steps either
upwards or downwards.
Remote command:
SPAN
The SPAN MANUAL softkey activates the window for manually entering the fre-
MANUAL quency span. The center frequency is kept constant. The overall allowed range of
span values is 1 kHz to 10 MHz.
It depends on the selected resolution bandwidth of the bar graph measurement: the
span is limited to ten times the resolution bandwidth.
Remote command:
4.6.1 Level Display and RF Input Configuration – AMPT Key
The AMPT key is used to set the input attenuation, the preamplifier, the auto range
function and the display unit. These functions are explained in detail in section

In addition, the level display range for the IF analysis display can be set.
The level axis of the IF analysis display is automatically set to display the full
dynamic range of the IF analysis. The upper limit of the diagram is equal to the
upper limit of the bar graph. The lower limit of the diagram depends on the selected
resolution bandwidth of the IF analysis. Every time when a parameter is changed
which affects the bar graph limits, e.g. the input attenuation, the IF analysis diagram
is changed accordingly. With the softkeys GRID RANGE LOG MANUAL and GRID
