Boonton 4500B RF Peak Power Analyzer
Operation 4-59
4.13 REF Key and Ref > Menu
The REF function key activates the Ref > menu, which controls the horizontal reference lines. Figures 4-30 and 4-31, and
Tables 4-13 and 4-14 describe the Ref > menu and its submenus.

(Type) Selections (SCPI cmd)
Ref Line 1
Pulse, Mod & Stat Controls position of reference line 1.
(Numeric) Continuous Range
The reference line will indicate the amplitude
level that corresponds to its display position
based on the reference channel‘s vertical
scale, vertical offset and units.
Ref Delta Pulse, Mod & Stat Displays the difference between the amplitude
(None) NONE levels at reference lines 1 & 2.
Ref Line 2
Pulse, Mod & Stat Controls position of reference line 2.
(Numeric) Continuous Range
The reference line will indicate the amplitude
level that corresponds to its display position
based on the reference channel‘s vertical
scale, vertical offset and units.

Note
When REF > Ref Tracking is active, Ref Line 1, Ref Line 2 and Ref Line Delta
will be dimmed and not adjustable. The Tracking Mode will automatically set
their position.
REF CH Sel Pulse, Mod & Stat Assign reference lines to a channel
(Mult. Choice) Off, Active, CH1, CH2,
Ext Trig 1, Ext Trig 2, The reference lines indicate power (or Fig. 4-30. Ref > Menu
Mem 1, Mem 2, voltage) level based on position on the
CH Math display grid. The relationship between
dependent on the vertical the screen position and the level is scale and
offset of the assigned channel. To make measurements on any specific
channel, that channel must be selected, or for a pair of channels, both
must have the same vertical scale, vertical center and units.
