Tip
A rectangle with 32 black elements in the matrix view indicates a failure with a single
transceiver board. The tooltip will indicate which board that fails. Restarting the CS90
system will normally fix the problem.
Failure of a number of consecutive transceiver boards indicates a problem with the power
supply.
• Weak signals indicate a problem with the supply power to the analogue amplifiers.
• No response indicate a problem with the supply power to the digital circuitry.
• A failure in the high voltage power supply to the transmitter circuitry can only be
detected in the transmit test.
Details
Mode
Select the operating mode of the diagnostic system.
• Select
None/freeze
when you have received the data and wish to freeze the
presentation for a closer study of the results.
• Select
Element amplitude
to start the test.
• Select
Element phase
to start the test and observe the element phases.
Start Averaging
The test process collects
data from all the channels,
and calculates the average
value. It may often be
useful to start the data
collection after the end
of the transmit pulse. Use
Start Averaging
to select
the first sample to be
part of the data collection.
Which samples to use,
and how many, depends
on the purpose of the test.
Use
Averaging Range
to select the number of
samples to be included in the data collection.
