Measurement Mode Selection – MODE Key 
The  MODE key provides a quick access to the menu of the current measurement mode and a fast 
change of the measurement mode. You can choose from the following measurement modes:  
• Spectrum Analyzer mode 
• Analog Demodulation mode (Analog Demodulation option, K7) 
• Bluetooth mode (Bluetooth Measurements option, K8) 
• Cable TV Analyzer mode (Cable TV Measurements option, K20) 
• Noise mode (Noise Figure Measurements option, K30) 
• 3G FDD BTS mode (3GPP Base Station Measurements option, K72) 
• CDMA2000 BTS Analyzer mode (CDMA2000 Base Station Measurements option, K82) 
• 1xEV-DO BTS Analyzer mode (1xEV-DO Base Station Measurements option, K84) 
• WLAN mode (WLAN TX Measurements option, K91/K91n) 
• WiMAX mode (WiMAX IEEE 802.16 OFDM, OFDMA Measurements option, K92/K93) 
To change the measurement mode 
1. Press the MODE key. 
The menu of the current measurement mode is displayed and the Measurement Modes dialog box 
is opened. 
2.  To activate another mode, select the corresponding option and press the CHECKMARK key. More 
than one measurement mode can be activated simultaneously. 
3.  To deactivate an activated mode, select the corresponding option and press the CHECKMARK 
key. 
Spectrum Analyzer mode 
In the Spectrum Analyzer  mode the functions provided correspond to those of a conventional 
spectrum analyzer. The analyzer measures the frequency spectrum of the test signal over the selected 
frequency range with the selected resolution and sweep time, or, for a fixed frequency, displays the 
waveform of the video signal. This mode is set in the initial configuration. 
Analog Demodulation mode (Analog Demodulation option, K7) 
The  Analog Demodulation  mode requires an instrument equipped with the corresponding optional 
software. This mode provides measurement functions for demodulating AM, FM, or PM signals. For 
details refer to "Analog Demodulation (Option K7)" on page 4.140. 
Bluetooth mode (Bluetooth Measurements option, K8) 
The Bluetooth mode requires an instrument equipped with the corresponding optional software. This 
mode provides measurements to test the conformity of signal sources to the Bluetooth RF Test 
Specifications. For details refer to "Bluetooth Measurements (Option K8)" on page 4.158.
