Baseband Digital IQ-Output (Option R&S SMU/SMJ-B18)
The number of necessary measurement depends on the number of installed R&S -B18, see following
table:
Installed paths
1 x BB 2 x BB
I/Q output: frequency response and amplitude-equality
Number of measurements
1 x 2 x
Test equipment
- Signal generator (Table 1-1, item 4), equiped with Digital Input (B17)
- Cable for Digital-Baseband IO (Table 1-1, item 14),
Test setup
 Connect signal generator’s Digital Input to the Digital Output of
the DUT with the Mini D Ribbon cable.
Test method
Set the Digital Output of the DUT in test sequence transmitting mode.
The signal generator's Digital Input evaluates the incoming test pattern
and calculates the Bit Error Rate.
Measurement  Settings on DUT
Activate test sequence transmitting via remote control with
command :TEST<HW>:BBOut:TX:STATe ON
Settings on signal generator
Start bit error evaluation via remote control with command:
:TEST<HW>:BBIN:RX?
Result:
0 = TestOk,
1 = TestFailed
Test will take 2 seconds to deliver a result. Repeat it 3 times, all of
the test results must be OK.
 Settings on DUT
Deactivate test sequence transmitting via remote control with
command :TEST<HW>:BBOut:TX:STATe OFF
Remark: <HW> = 1 for path 1, 2 for path 2
