Index Description

Status Indicator: This indicator (asterisk) is displayed when the current instrument setup does not correspond to the one which was applied when a trace is displayed. This happens when:

1The instrument setup is modified when the Sweep mode is set to Single and a new sweep has not yet been triggered.

The instrument setup is modified in the middle of a measurement. The measurement is re-started with the new setup and this indicator is shown until the entire trace is re-written.

2Y-axis Scale: The Y-axis scale is labeled every other major grid line.

3Sweep Status: Displays the sweep status of Triggered and Single sweep modes.

Trace Information: Trace information is displayed in the following format (the current active trace has the text underlined):

4 to 8

Trc<n> <Trace Mode>

<Detector Mode>

<Trace Math>

Where:

n:Trace Number (1 to 5)

Trace Mode: Trace Mode (Clear Write, Max Hold, Min Hold, Average, View, or Off)

Detector: Detector Type (Auto, Normal, Maximum, Minimum, Sample, Average, or RMS)

Trace Math: Trace Math indicator (available when Trace Mode: Average is selected)

9	Sweep Mode: This field is used to display the sweep modes of Swept, FFT (Fast Fourier Transform), or
	FFT-WB (Wideband).
10	Start Frequency: Indicates the start frequency of the sweep.
11	Frequency/Division: This field indicates the horizontal scaling per division.
12	Center Frequency: Indicates the center frequency of the sweep. If a frequency offset is set, OFFSET is
	also displayed.
13	Span Frequency: Indicates the total span of the frequency sweep.
14	Stop Frequency: Indicates the stop frequency of the sweep.
15	Trace Display: Up to five traces can be displayed using the following colors: Trace 1--Yellow, Trace 2--
	Green, Trace 3--Cyan, Trace 4--Magenta, Trace 5--Red
16	Marker Display: Markers are annotated with the absolute power level next to the marker location.
17	Marker Display: Markers are annotated with the absolute power level next to the marker location.
18	Display Line: A display line may be displayed at any desired level.
	Active Marker Field: The active marker number, frequency, and amplitude values are displayed in this
19	field. The trace that has received the marker is indicated in brackets. If the Marker is a Delta Marker, the
	delta symbol (D) precedes the Mkr number and the values displayed are relative to the reference
	marker.
20	Reference Marker Field: The reference marker number, frequency, and amplitude values are displayed
	in this field. The displayed values are absolute in magnitude.
21	Bandwidth Setup: The bandwidth setup field displays the current Resolution Bandwidth, Video
	Bandwidth, and Sweep Time settings. If the settings are manually entered, an asterisk is displayed.
22	Amplitude Setup: The amplitude setup field displays the current attenuation level, reference level, and
	reference level offset. If the attenuation is set manually, an asterisk is displayed.
