Mobile Phone	To measure an incoming signal from the mobile phone’s transmitter, perform the
Transmitter Testing	following steps:
Using Test Mode

•Select TEST MODE.

•In theExpected Input area, (2), see Figure 2-3 on page 2-10, enter the GSM channel number of the signal to be measured. This will automatically update the input Frequency field below it, (3), see Figure 2-3 on page 2-10. If a frequency needs to be measured which does not correspond to a standard GSM channel, enter the non-standard value into the Frequency field. This value can be anywhere from 10 MHz to 1000 MHz. A direct entry in the Frequency field over-rides the frequency defined by the Channel field above.

•Enter the expected transmit level of the mobile phone in the TX Level field. This will automatically update the Amplitude field below with the equivalent TX level represented in dBm. If a non-standard input level is expected, enter the value directly into the Amplitude field, this overrides the TX Level field above.

•Enter the expected Colour Code of the input signal. The Colour Code is a function of the central “midamble” of the transmitted burst and is needed so that measurements are correctly synchronized to the received burst. If the Colour
