Once again, the features on this screen are very similar to the VNA screen shown previously. This
screen is displayed for dual-port (S21) measurements. The left scale will always be GAIN in dB, and
the right scale will always be PHASE in degrees (although it is possible to turn this trace off, if
desired).
Keypad Operations
Power ON/OFF
The ON/OFF key
is used to power the instrument on and off. There are different ON/
OFF sequences; Normal for starting with using the last settings at power down or Soft
Reset for starting with default settings.
POWER ON
– Press the ON/OFF key for one second.
A splash screen with AEA Technology’s logo and Version information will appear for several seconds.
It will then open to the test screen in use at the time it was normally or automatically powered down.
Keypad Power ON indication: LED lit
NORMAL POWER DOWN
– From any Measurement screen, Press and hold the ON/ OFF key for
one second. Power Down sequence will start within one second later. This power down sequence
saves all the settings for resuming testing on the next Normal Power On press.
The BATTERY SAVER Auto-Power Down is a normal power down and saves all the settings also.
HARD POWER DOWN
– Press and hold the ON/OFF key for ten seconds. This forces the BRAVO
EX2 to shut down and should be used if:
A.
The unit will not power down with a Normal Power Down (1 second hold of the key).
B.
If the BRAVO EX2 is not performing correctly, menus or cursor keys do not work, or the
measurement screen does not appear correctly formatted.
NOTE:
A Hard Power Down will NOT save the current settings as their data/data corruption may be causing
the firmware issue. If a Hard Power Down needs to be executed the next power on should be the Soft Reset
procedure to perform firmware housekeeping and restore normal operation.
Soft Reset
With the BRAVO EX2 OFF, Press and hold the ENTER key
Press and release the ON/OFF key to power the BRAVO EX2 ON.
After power comes on... (~1 second) release the ENTER key
Display will allow you to confirm reset to factory default settings.
When Measurement Screen appears you can recall a saved setting or set desired settings
