AMPLITUDE Y Scale

Activates the reference level function, if it is available, and accesses the amplitude
menu keys. Amplitude menu keys are used for setting functions that affect the way
data on the vertical axis is displayed or corrected.
Ref Level This key allows the reference level to be changed. This function is activated when

voltage represented by the top graticule line on the display. Changing the value of
the reference level changes the absolute amplitude level (in the selected amplitude
units) of the top graticule line. The reference level can be changed using the step
keys, the knob, or the numeric keypad. Pressing any digit, 0 through 9, on the
numeric keypad brings up the terminator menu.
Sets the input attenuation in 5 dB increments. The analyzer input attenuator, which

is normally coupled to the reference level control, reduces the power level of the
analyzer input signal at the input mixer. Attenuation can be changed using the step
keys, the knob, or the numeric keypad.
NOTE Step keys and knob can not be used to set Atten = 0. To set the attenuator to 0 dB
you must use the keypad.
To prevent damage to the input mixer, do not exceed a power level of +30 dBm at

the input. To prevent signal compression, keep the power at the input mixer below
0 dBm. With the attenuator set to Auto, a signal at or below the reference level will
result in a mixer level at or below –10 dBm.
Sets the units per vertical graticule division on the display. Scale/Div values may

range from 0.1 to 20 dB per division when working on a Monitor Spectrum
measurement.
When working in I/Q Error (Quad View), the screen is divided into four quadrants,
three of which show a measurement trace. The units of measurement vary from
trace to trace, and so consequently do the units per division on the graticule, or the
Scale/Div.

Ref Value When working in I/Q Error (Quad View), the screen is divided into four quadrants,
three of which show a measurement trace. The reference position on each trace is
indicated by a small chevron at either side of the graticule. The Ref Value softkey
allows you to specify the value of this reference position in units of measurement
which vary from trace to trace. This softkey is only available in I/Q Error (Quad
View).
