If the receiver power check fails after calibration:
1. Ensure the Installation Calibration and Smart Cal have been completed,
calibrating both source and receiver power.
2. Verify that the power sensor is accurate and not damaged, especially at
3. Verify the condition of the Calibration Kit components. If cleaning is
4. Ensure the power meter is setup correctly.
If the receiver power is not m13 dBm, ± 1 dB, mean:
1. Confirm power input using a power meter. See
Procedure to Measure
VNA Output on Cables
(RF/LO or LO)
at the top of this page.
2. The VDI extenders need +2 dBm (10-15 GHz) at the RF/REF IF input to
reach full power output. Verify the cable has + 2 dBm to the extender
port tested when the VNA power level is set to +20 dBm.
3. Verify that the LO Input at the end of the cable is at least -7 dBm (10-15
GHz).
4. Verify the condition of the Calibration Kit components. If cleaning is
Procedure to Measure VNA Output on Cables (RF/Ref or LO)
1. Setup sweep type CW
2. Select frequency 75 GHz (center of WR12 band) or center of band if
using an alternative configuration.
3. Points = 1
4. Set power to +20 dBm
5. Measure with power meter. Connect power meter to end of cable. Verify
2 dBm on LO/RF
RF LO and IF cables can be measured using the VNA in its standard configuration.
•
RF LO cables:
10-15 GHz, 2 dB loss max
•
IF cables (10 MHz): 10-15 GHz, 1 dB loss max
Not performing an installation calibration will result in a source power calibration failure.
Refer to the VDI website at
https://www.vadiodes.com/en/products/vector-network-
analyzer-extension-modules
for VDI extender information.
If an extender or the Calibration Kit is suspected, it will need to be returned to the
vendor for service. Both VDI extenders must be returned in their transport case.
If your issue is not component specific and is still unresolved, it is recommended that
you
for assistance or return the entire system to Keysight.
-4 to +2 dBm input, 10-15 GHz, -3 dBm max output, ~ 4 MHz
-10 to +13 dBm, 10-15 GHz
