PXIe-5673E Calibration Procedure | © National Instruments | 23
Note
Harmonic, subharmonic, and non-integer harmonic levels outside the device
frequency range are typical.
If the results are within the selected test limit, the device has passed this portion of the
verification.
Verifying Baseband Linearity-Related Spurs
Complete the following steps to verify the baseband-related spur levels of the PXIe-5673E using
a spectrum analyzer.
1.
Connect the PXIe-5611 RF OUT front panel connector to the spectrum analyzer RF INPUT
front panel connector through the SMA(m)-to-SMA(m) cable.
2. Connect the PXIe-5650/5651/5652 REF IN/OUT front panel connector to any rubidium
frequency reference rear panel BNC connector through the BNC(m)-to-SMA(m) cable.
3. Connect any available rubidium frequency reference rear panel BNC connector to the
spectrum analyzer REF IN rear panel connector through the BNC(m)-to-BNC(m) cable.
4. Generate a single-sideband tone with a +1 MHz offset from the carrier signal with the
following niRFSG property settings:
•
Frequency (Hz): 85 MHz
• Power Level (dBm): 0 dBm
• Generation Mode: Arb Waveform
• Reference Clock Source: RefIn
