Programming a TDSO Frame Error Rate Measurement

This section provides an example of how to make an TDSO (Test Data Service Option) FER measurement via
GPIB.
The following program example assumes that the mobile station's antenna output is connected to the RF
IN/OUT connector, and the mobile station has found service.
The basic procedure to test Loopback BER is as follows:
1. Make a SO 32 (F-SCH) call (see
2. Configure the TDSO FER Setup parameters using the
3. Start the FER measurement using the
4. Use the "FETCh:CFERror"
