Table 7. PXIe-5624 IF Digitizer Front Panel Connectors
Connector
Use
IF IN
Connects to the IF OUT connector on the PXIe-5606 front panel. This
connector is the input terminal for a frequency-translated IF waveform from
the RF downconverter, filtered by the PXIe-5606, for digitization and
measurement. IF IN is an SMA connector with a nominal input impedance of
50 Ω. When used in a PXIe-5668 the IF IN connector has a +6 dBm full-scale
input level and a -6 dBm nominal input level. The IF IN connector damage
level is +20 dBm.
CLK IN
Connects to the LO2 OUT connector on the PXIe-5606 module. The CLK IN
connector is the input terminal for the Reference or Sample Clock (ADC
Clock). CLK IN is an SMA connector with a nominal input impedance of
50 Ω.
CLK OUT
The CLK OUT connector is the output terminal for the PXIe-5624 PLL
Reference or Sample Clock (ADC Clock). CLK OUT is an SMA connector
with a nominal output impedance of 50 Ω. The output power delivered to a
50 Ω load is >10 dBm.
PFI 0
Receives a digital trigger from an external source. PFI 0 is an SMA connector
and has LVTTL.
DIGITAL I/O DIO terminal that contains general-purpose DIO signals. DIO lines are not
accessible using NI-RFSA.
Caution
The DIGITAL I/O connector accepts a standard, third-party HDMI
™
cable, but the DIGITAL I/O port is not an HDMI interface. Do not connect the
