Selecting a Mode

The Mode menu key is used to select the measurement personality you have purchased with your instrument, or to select the basic or service modes, which are native to the instrument. Upon turn-on the instrument will default to the basic mode.

•Mode - Accesses the measurement personality mode. Press the key that corresponds to the mode you want to select, such as GSM or cdmaOne. For a full explanation of the personality mode you have purchased, see the documentation which comes with that option.

•Basic - This mode is useful for making measurements that are not preset to industry standards. They can be used for troubleshooting your devices. Press Mode, Basic to switch to the basic mode, and bring up the measurements menu. For more information on these measurements go to “Basic Measurements” on page 88.

•Service These features will help you check the functionality of your instrument. Press Mode, Service, to switch to the service mode, and bring up the service measurements menu. Features accessed through this menu include tests which check the timebase frequency, the sensors on the RF board, and the functionality of the front panel keys. For more information on these features go to “Service Measurements” on page 141.

The basic waveform and spectrum measurements are available as well as a power vs time measurement which is used only for self-diagnostic purposes. The measurement setup parameters that you select while in Service mode are only used for service mode. The Basic mode settings are independent. Descriptions of the spectrum and waveform measurements begin on page 97.

Note that spectrum and waveform measurements are available in each personality mode, as well as in the basic and service modes. Each with their own independent mode settings.

Press Preset to set the instrument to a known factory default state. This sets all parameters to their factory default values for the selected mode. Preset does not switch the modes.

Some features are intended for use only by service personnel and cannot be accessed without a password. If after pressing a key, a message appears requesting entry of a password, this means that the feature is meant for service use only. The password is only available through the service guide.
