The "External LVDS Test" is used to check the correct data transmission of the digital
baseband outputs (BBOUT).
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 alterna-
tively 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.
Parameters:
<LRate> float
Range:
66E6 to 100E6
Increment: 1E6
*RST:
100E6
Example: TEST:BBOut:LRATe 90MHZ
sets the LVDS interface rate to 90 MHz
Manual operation: See "BBOUT LVDS Rate" on page 139
:TEST<hw>:BBOut:TTESt[:STATe] <State>
Activates the transmission of a known pseudo-random sequence (On).
Parameters:
<State> 0 | 1 | OFF | ON
*RST:
0
Example: TEST:BBO:TTES:STAT ON
starts the transmission of a signal test sequence .
Manual operation: See "Tx Test" on page 139
:TEST:CONNector:AUXio?
The command triggers a test of the AUX IQ interface (see Service Manual Instrument,
section "Performance Test"). This function is only available via remote control.
Example: TEST:CONN:AUX?
Usage: Query only
:TEST<hw>:DIRect <HW_assembly>,<subadress>,<hex data string>
:TEST<hw>:DIRect? <HW_assembly>,<subadress>
The respective hardware assembly responds directly to the command; any safety
mechanisms are bypassed. This function is only available via remote control.
