Execute BBIN A/B Selftest
Performs a selftest on the baseband input hardware options. Several analog diagnostics
points are checked to verify the correct function of the module. The result (succeeded or
failed) is displayed in the status field next to the "Execute BBIN: x Selftest" button.
SCPI command:
:TEST:BBIN on page 796
BBOUT LVDS Rate
Sets the interface speed.
The "External LVDS Test" is used to check the correct data transmission of the digital
baseband outputs (BBOUT) and the correct data reception of the digital baseband inputs
(BBIN).
An external cable connection is needed to perform this test successfully. An output must
be connected to an input with the digital I/Q cable. Always an input/output pair is tested
together. The input and the output can be on the same instrument, or alternatively on two
different instruments. Given an arbitrary cable connection, the appropriate Tx test can be
activated with different interface speeds (LVDS rate).
On the connected input, this test sequence is received and can be compared with the
expected test signal.
SCPI command:
:TEST<hw>:BBOut:LRATe on page 797
Tx Test
Activates the transmission of a known pseudo-random sequence (On).
SCPI command:
:TEST<hw>:BBOut:TTESt[:STATe] on page 797
BBIN Get Rx Bit Error
Performs a bit error rate test of the received test signal. The result (succeeded or failed
is displayed in the status field next to the "BBIN: GET Rx Bit Error" button.
SCPI command:
:TEST<hw>:BBIN:RBERror on page 796
