PC Power meter calibration is on. (For power meter calibration
procedures, refer to the “Calibrating for Increased Measurement
Accuracy” chapter of the user’s guide.)
PC? The analyzer's source could not be set to the desired level, following
a power meter calibration. (For power meter calibration procedures,
refer to the “Calibrating for Increased Measurement Accuracy”
chapter in the user’s guide.)
P? Source power is unleveled at start or stop of sweep.
P
↓ Source power has been automatically set to minimum, due to
receiver overload. (See POWER, in Chapter 4, “Hardkey and Softkey
Reference”)
PRm Power range is in manual mode.
Smo Trace smoothing is on. (See AVG and SMOOTHING in Chapter 4,
“Hardkey and Softkey Reference”)
tsH Indicates that the test set hold mode is engaged. That is, a mode of
operation is selected which would cause repeated switching of the
step attenuator, or a mechanical switch. This hold mode may be
overridden. See MEASURE RESTART, or NUMBER OF GROUPS,
in Chapter 4, “Hardkey and Softkey Reference”
W/A Units of calibrated E/O measurements.
↑ Fast sweep indicator. This symbol is displayed in the status notation
block when sweep time is
≤1.0 second. When sweep time is ≥ 1.0
second, this symbol moves along the displayed trace.
* Source parameters changed: measured data in doubt until a
complete fresh sweep has been taken.
4. Active Entry Area. This displays the active function and its current value.
5. Message Area. This displays prompts or error messages.
6. Title. This is a descriptive alphanumeric string title that you define and enter through an attached
keyboard or as described in the user’s guide.
7. Active Channel. This is the label for the number for the active channel, selected with the Chan 1, Chan
2, Chan 3, and Chan 4, keys.
If multiple channels are overlaid, the labels will appear in this area. The active channel is denoted by a
rectangle around the channel number.
For multiple-graticule displays, the channel information labels will be in the same relative position for each
graticule.
NOTE The label of the active channel is enclosed in a rectangle to differentiate it from inactive
channels.
8. Measured Input(s). This shows the parameter, input, or ratio of inputs currently measured, as selected
using the Meas key. Also indicated in this area is the current display memory status.
9. Format. This is the display format that you selected using the Format key.
10. Scale/Div. This is the scale that you selected using the Scale Ref key, in units appropriate to the
current measurement.
11. Reference Level. This value is the reference line in Cartesian formats or the outer circle in polar
