Introduction

CW MEAS/AF ANALYZER

•A23 Input

•A19 Measurement

•A11 Receiver Mixer

•A16 Receiver

•A3 Audio Analyzer 1

•A2 Audio Analyzer 2

•A4 Modulation Distribution

The CW measurements are power and frequency. For the power measurement, the detector is in the A23 Input assembly and is measured by the voltmeter in the A19 Measurement assembly. The AF analyzer measurements are either demodulated signals that pass through the A23 Input, A11 Receiver Mixer, and A16 Receiver assemblies or internal and external audio signals that pass through the A4 Modulation Distribution assembly before being routed to the A3 Audio Analyzer 1 assembly. The A3 Audio Analyzer assembly either passes the signals to the A19 Measurement assembly or to the A2 Audio Analyzer 2 assembly before routing to the A19 Measurement assembly. After the measurement is done the measurement numbers are sent to the A7 Controller to be sent to the display section.

SCOPE

The oscilloscope has the AF analyzer as a front end so the routing configurations that can be done for the AF ANALYZER are also possible for oscilloscope measurements. The A19 Measurement assembly makes the oscilloscope measurements. After the measurement is done the measurement numbers are sent to the A7 Controller to be sent to the display section.

SPEC ANL

•A23 Input

•A11 Receiver Mixer

•A16 Receiver

•A18 Spectrum Analyzer

•A19 Measurement

The spectrum analyzer signal receives its signal from the RF input stages after the signal is converted to a 114.3 MHz IF in the A16 Receiver assembly. The A18 Spectrum Analyzer assembly works together with the A19 Measurement assembly. The A18 Spectrum Analyzer receives sweep and trigger signals from the A19 Measurement assembly and returns analog level signals to the A19 Measurement assembly. The A19 Measurement
