Measurement Theory

Introduction

DSP ANL

•A23 Input

•A11 Receiver Mixer

•A16 Receiver

•A9 Global Test and Demod

The DSP analyzer measurements digitally analyze the signal under test. The signal is leveled and converted to a 10.7 MHz IF and routed to the A9 Global Test and Demod assembly where the signal is digitized and the actual measurements are made. After the measurement is done the measurement numbers are sent to the A7 Controller to be sent to the display section.

OUT RF SP

•A23 Input

•A11 Receiver Mixer

•A16 Receiver

•A18 Spectrum Analyzer

•A19 Measurement

The output RF spectrum is a GSM required measurement that is a zero span spectrum analyzer measurement at specific offsets from the carrier frequency. Refer also to the SPEC ANL description.

PULSE

•A23 Input

•A11 Receiver Mixer

•A16 Receiver

•A18 Spectrum Analyzer

•A19 Measurement

The pulse measurement is used to measure the −70 dB point of a GSM pulse because the DSP analyzer will only measure to −30 dB. This is a spectrum analyzer measurement. Refer also to the SPEC ANL description.
