... Colpitts oscillator circuit has been included on the SL6649-1. The Colpitts oscillator and channel filters use the same type of architecture, hence there is a direct correlation between oscillator frequency and cut off frequency. By knowing the Colpitts oscillator frequency the channel filter cut off frequency can be estimated from Figure 4 ...

... METHOD FOR THE MEASUREMENT OF SENSITIVITY ON THE SL6649-1 RECEIVER The method used by GEC Plessey Semiconductors in the measurement of terminal sensitivity is essentially the same as that described in the CEPT Res 2 Specification. This method requires the following equipment signal generator e.g. HP8640 2. A pocsag encoder 3. A pocsag decoder e.g. MV6639 4 ...
