 | REF LEVEL Sets the reference level of the top graticule line in the selected units. If the reference level offset is not zero, OFFSET REF LEVEL is displayed at this location. Refer to Setting Amplitude Parameters. SECOND REF LEVEL The reference level is the top graticule line to the right on the measurement display. Its functionality is exactly same as reference level, but it is only available when trace math is enabled. SCALE/DIV Sets the graticule scale/division for log-based units. This setting does not apply to linear units SECOND SCALE/DIV It applies to second reference level and is available only when trace math is enabled. REF LEVEL OFFSET Sets the reference level offset in dB units. This setting can compensate for the presence of external input attenuation or gain. FREQ OFFSET Accounts for frequency conversions outside of the analyzer. Refer to Setting Frequency Parameters. ATTEN LEVEL When auto attenuation is off, sets input attenuation. PRE AMP Toggles the low-noise front-end preamplifier on or off. Refer to Setting Amplitude Parameters. TRACES/CURSORS Displays the current status of up to six traces or cursors in a quick-view summary. When the measurement view is set to RF Spectrum, trace information is displayed in this area. When the measurement view is set to Spectrogram, cursor information is displayed in this area. Cursors are available in the Spectrum measurement with the Spectrogram view selected. The summary information includes the trace or cursor number, type, mode, and detector type. The active trace will show a highlighted background with the mode and detector type restated under the table. In Spectrogram, a reference trace (T0) will show you the settings of the trace used to fill the spectrogram. The reference trace settings are applied to all traces and cursors while in Spectrogram view. Selecting a trace or cursor in the summary panel activates the pressed trace or cursor and opens the TRACE menu, allowing you to select and set up an individual trace or cursor as desired. Refer to Setting Trace Parameters. SWEEP Toggles the current sweep setting between continuously or sweep once. Refer to Setting Sweep Parameters. FREQ REFERENCE Indicates the current frequency reference source of Internal High Accuracy (used after GPS has lost sync, but while the internal clock still has good GPS reference), Internal Standard Accuracy, External, or GNSS (GPS) Hi Accy (requires GPS). The instrument automatically selects the frequency reference in the following order of priority: external, GPS, then the internal time base. | |
