Performance Check
Verify the system is properly set up.
It is recommended to measure the following parameters for ensuring that the block up converter is in
good working condition:
-
Gain and Gain flatness
-
RF load VSWR and RF source VSWR
-
Two-Tone Inter-modulation Distortion
-
Return Loss at connectors of the block up converter
Using a Source and an IF input signal level within the small signal region of the block up converter,
measure the power level at connectors IF or MS connector. Plot the swept response on a test data sheet.
From the plot, determine gain and gain flatness.
Plot the swept return loss for both the IF Input and RF Output signals on a test data sheet. From the plot
determine the return loss.
From the output power measurements determine rated output power. Record value on a test data sheet.
Measure the Two-tone Inter-modulation Suppression using two equal signals separated by 5 MHz.
Record value on test data sheet.
Cable connection and disconnection shall be done carefully to avoid
physical damage to the cables and connectors, which may cause
intermittent problems in the future.
A non-warranty and out-of-warranty repair service is available from Actox Corporation for a nominal
charge. The customer is responsible for paying the cost of shipping the BUC both to and from Actox
Corporation for these repairs.
Symptom Action
Fails performance test
Check power source, RF source, cabling and connectors. Check LED indicators for
status and if the light is red contact Actox Corporation. If we are not able to assist
you remotely, return block up converter to Actox Corporation after RMA number
has been issued.
