AMPLITUDE Displays the amplitude or scale menu depending on the measurement mode.
Amplitude
Menu
Provides for changing the display scale. Selected values may be changed using
the Up/Down arrow key or keypad.
Choosing
AMPLITUDE in FREQ or DTF measurement modes causes the soft
keys, below, to be displayed and the corresponding values to be shown in the
message area.
q
TOP — Opens the top parameter for data entry and provides for setting the
top scale value. Press
ENTER when data entry is complete.
q
BOTTOM — Opens the bottom parameter for data entry and provides for set
-
ting the bottom scale value. Press
ENTER when data entry is complete.
Choosing
AMPLITUDE in SPECTRUM ANALYZER mode causes the soft keys,
below, to be displayed and the corresponding values to be shown in the message
area.
q
REF LEVEL — Activates the amplitude reference level function.
q
SCALE — Activates the scale function in a 2 through 15 dB logarithmic am
-
plitude scale.
q
ATTEN — Sets the Anritsu input attenuator so that it is either coupled auto
-
matically to the reference level (
AUTO) or manually adjustable (MANUAL).
q
UNITS — Choose from the menu of amplitude related units. Selection of
dBm sets absolute decibels relative to 1 mW as the amplitude unit. Selection
of dBV, dBmV or dBmV sets absolute decibels relative to 1 volt, 1 millivolt,
or 1 microvolt respectively as the amplitude unit.
q
REF LEVEL OFFSET — Sets the reference level offset. This feature allows
measurement of high gain devices in combination with an attenuator. It is
used to offset the reference level to view the correct output level. For exam-
ple, to measure a high gain amplifier with an output of 70 dBm, an external
50 dB attenuator must be inserted between the Site Master and the device. To
compensate, set the reference level offset to –50 dB to set the level at the top
of the display.
