RECALL SETTINGS
Press ENTER to open a list of saved instrument setting files.
NOTE: When SAVE SETTINGS is invoked, the entire instrument state is saved-- This INCLUDES the
current calibration, if FREQUENCY-SPECIFIC calibrations are in use! These appear as files with the
.SET extension.
When test results are recalled via DATA RECALL, the stored trace is displayed on screen. Press ESC
to return to the MEMORY menu.
When you are done with MEMORY operations, press ESC to exit Memory Menu.
Measurement and Support Screens
General Information
The Bravo EX2 Analyzer has the following screens:
Measurements:
SWR
– switchable via repeat presses of the SWR/RL Key Return Loss – switchable via repeat
presses of the SWR/RL Key
VNA
-- Complex impedance analysis.
CW Mode
– Continuous Wave mode
Support:
Frequency Setting
– Both Start-End and Center Frequency & Bandwidth (Span) Screens
Frequency Specific Calibration Screens
– Calls a series of Prompt screens to attach the
Open, Short, and Load Terminators, followed by using ENTER to process calibration data for
each terminator. After processing the Load Terminator the calibration process is completed and
the BRAVO EX2 returns to the selected measurement screen.
BROADBAND CAL
– Calls a series of prompt screens to attach the Open, Short, and Load
Terminators, followed by using ENTER to process calibration data for each terminator. After
processing for the Load Terminator is complete, the calibration process is completed and the
BRAVO EX2 returns to the selected measurement screen.
NOTE:
BROADBAND CAL can be used to perform the calibration process with or without a test lead,
antenna feed line, or adapter attached. If a test lead and/or adapter is attached during the broadband
calibration, those items are calibrated with the instrument. These MUST be attached to the instrument
for measurements using that calibration. If no test lead, antenna feed line, or adapters are attached
during the broadband calibration, only the BRAVO EX2 will be calibrated through to the N connector
and any items attached after that will be part of the measurements.
Measurement Screens
In general all the measurement screens provide either a graphic representation of the measurement
parameter(s) selected (Sweep mode) or a fast changing digital readout (CW mode). The support
screens are designed for entering various settings or saving and recalling test results from the
memory.
Scales can be changed by pressing the UP arrow key to highlight the desired measurement
parameter, then press the Scale key repeatedly to selected the desired preset scale. In the case of
SWR or RL there is only one scale on the left, so the Scale key can be used at any time to adjust the
measurement screen’s SWR or Return Loss scale.
