Table 6. NI 5624R IF Digitizer Front Panel Connectors
Connector Use
IF IN Connects to the IF OUT connector on the NI 5606 front panel. This
connector is the input terminal for a frequency-translated IF waveform from
the RF downconverter, filtered by the NI 5606, for digitization and
measurement. IF IN is an SMA connector with a nominal input impedance of
50 Ω. When used in a NI 5668R 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 NI 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 NI 5624R 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
