4530 Series RF Power Meter Operation
3.6.1 Entry. When the Text key is pressed, the 4530 enters Text Mode.
3.6.2 Measurement Page Selection. Pressing the
∧∧∧∧∧ ∨∨∨∨
or
∨ keys while in Text Mode pages up or down through a
series of pages that contain all the measurements being performed in the current mode. See paragraph 3.9
(Display Formats) for a list of what measurements are displayed in each format.
3.6.3 Channel Selection . Pressing the < or > keys while in Text mode switches the display between channels.
The keys toggle the display between “CH1 < > BOTH < > CH2”. In addition to the primary measurement, the
CH1 and CH2 displays may show a number of secondary measurements for that channel. The BOTH display
format shows the primary measurements only in the main display window, along with an optional bargraph. In
some cases, secondary measurements for each channel may appear in the header. Single-channel units
(Model 4531) can only page between the CH1 and BOTH display formats. See paragraph 3.9 (Display
Formats) for a list of what measurements are displayed in each format.
3.6.4 Measurement Control. Pressing Enter/Run while in Text Mode starts the measurement if it is stopped, or
arms the trigger if single-sweep mode is active. Pressing ESC/Stop stops the measurement if it is running and
holds the current measurement values. Once stopped, pressing ESC/Stop again clears the measurement
result, and resets for a new measurement. Anytime measurement is stopped, you can change display settings
or certain measurement parameters, and the current measurements displayed are updated accordingly.
3.6.5 Parameter Editing from Text Mode. Pressing Text while already in Text Mode will enter Edit mode for the
first active channel. The screen’s measurement window continues to display and update the active measure-
ment, but the two-line header area at the top of the screen is used as an edit window. Pressing Text again
switches to Edit Mode for the second channel, if active. Another press of the Text key will return to normal
Text Mode. See paragraph 3.8 (Edit Mode Operation) for more details.
3.7 GRAPH MODE OPERATION
Graph Mode is used to present the current measurements in a real-time graphic or trace-type format. This can be a plot
of signal amplitude (usually power) versus time, similar to an oscilloscope screen, or power versus percent probability.
Power is always presented on the Y-axis, while time or probability is on the X-axis. Both axes can be scaled, and vertical
or horizontal cursors can be positioned on the trace to perform measurements at specific time or percent offsets of each
cursor or in the region between the two cursors.
