3.1 Complex Spectrum Measurement
Couplings When "Auto Scaling" on page 150 is ON (default), this value is automatically determined by the
measurement result. When you set a value manually, Auto Scaling changes to OFF
In Complex Spectrum, unlike some measurements, Attenuation is not coupled to the Ref Value
Preset 0.00 dBm
State Saved Saved in instrument state
Min/Max -250.00 dBm / 250.00 dBm
Annotation Ref <value> is at the top left of the graph
Scale/Div
For measurements that support a logarithmic Y-Axis Scale/Div, this control enables
you to set the height of one division of the graticule in the current Y-Axis unit.
This function also determines the displayed amplitude range in the log plot graph.
Since there are usually 10 vertical graticule division on the display, the total
amplitude range of the graph is typically 10 times this amount. For example, if
Scale/Div is 10 dB, then the total range of the graph is 100 dB.

Command
Complex Spectrum:
:DISPlay:SPECtrum:VIEW[1]:WINDow[1]:TRACe:Y[:SCALe]:PDIVision <rel_ampl>
:DISPlay:SPECtrum:VIEW[1]:WINDow[1]:TRACe:Y[:SCALe]:PDIVision?
Streaming:
:DISPlay:STReaming:VIEW[1]:WINDow[1]:TRACe:Y[:SCALe]:PDIVision <rel_ampl>
:DISPlay:STReaming:VIEW[1]:WINDow[1]:TRACe:Y[:SCALe]:PDIVision?
Example
:DISP:SPEC:VIEW:WIND:TRAC:Y:PDIV 10
:DISP:SPEC:VIEW:WIND:TRAC:Y:PDIV?
Couplings In measurements that support "Auto Scaling" on page 150, when Auto Scaling is ON, this value is
automatically determined by the measurement result. When you set a value manually, Auto Scaling
automatically changes to OFF
Preset 10.00 dB / Div
State Saved Saved in instrument state
Min/Max 0.10 dB/20 dB
Annotation <value> dB/ left upper of graph ! all measurements unless noted
In log scale, the Scale/Div is shown in the upper left side of the display. In Lin mode, no annotation is
displayed
Ref Position
Enables you to position the reference level at the top, center, or bottom of the Y
Scale display. Changing the reference position does not change the reference level
value.
