TB8100 Calibration Kit

2. TB8100 Technical Training 27-28 July 2005
Introduction
The Cal Kit is a S/W utility that performs TWO functions:
“Frequnecy Alignment” and “Calibration”
Frequency Alignment:
Sets Tx & Rx VCO’s to required switching range
Tunes receiver front end to required frequency band
Only the reciter requires adjustments.
Simple and fast to perform.
Only require a Calibration Test Box (CTU)
Calibration:
Used to setup critical operational parameters to meet product specifications
ONLY required after component or PCB assembly replacement
Should never be required over a normal life time, ‘factory only’ process
Guarantees value accuracy of configuration S/W settings and measurments
Sets Audio levels, RSSI, VCO / Modulation flatness, PA output power etc
Complicated and requires minutes & Test set for a full re-calibration

Introduction
These TABs have been provided to allow servicing of the products
They should only be used when there is a major problem with the Reciter, PA or PMU. You may be asked to perform a re-calibration due to firmware upgrade / downgrade requirements.
This TAB allows the adjustment of the Reciter VCO’s and Receiver Front end.
