1.1 Operating Environment

1 INTRODUCTION

This maintenance manual is a complete service guide for the R3764AH/BH/CH, R3765AH/BH/CH R3766AH/BH/CH or R3767AH/BH/CH network analyzers. This manual contains information on basic theory, performance tests, diagnostic tests, adjustments and calibrations for these network analyzers.

1.1 Operating Environment

This section describes the environmental conditions and power requirements necessary to use the spectrum analyzer.

1.1.1 Environmental Conditions

These network analyzers should be installed in an area which satisfies the following conditions:

  • Ambient temperature: 0°C to +50°C (32°F to 122°F) (operating temperature)
  • Relative humidity: 85% or less (without condensation)
  • An area free from corrosive gas
  • An area away from direct sunlight
  • A dust-free area
  • An area free from vibrations
  • A low noise area

Although these network analyzers have been designed to withstand a certain amount of noise riding on the AC power line, it should be used in an area of low noise. Use a noise cut filter when ambient noise is unavoidable.

• An area allowing unobstructed air flow

These network analyzers have an exhaust cooling fan on the rear panel and an exhaust vent on the bottom side toward the front. Never block these areas as the resulting internal temperature rise will affect measurement accuracy.

1.1 Operating Environment

Figure 1-1 Operating Environment

These network analyzers can be used safely under the following conditions:

  • Altitude: 2000m maximum above the sea level
  • Installation category II

2.1 Overview

2 THEORY OF OPERATION

This chapter describes the basic operation of these network analyzers using block diagrams and flowcharts. These diagrams are not intended to provide information at a component level.

2.1 Overview

These network analyzer have the following frequency and level range. When Option 10 is installed, The output signal can be adjust between 0 dB and 70 dB.

The R3766AH/BH/CH and R3767BH/CH have the range of 3.8 GHz to 8.0 GHz added. A fixed value is set as its level within a range of 3.8 GHz to 8.0 GHz for the R3766AH/BH/CH and R3767AH/BH/CH. The Frequency and Level ranges are shown in below.

Types 40 MHz to 3.8 GHz 3.8 GHz to 8.0 GHz
R3764/65AH +17 dBm to -8 dBm N/A
BH +7 dBm to -18 dBm N/A
CH +10 dBm to -15 dBm N/A
R3766/67AH +17 dBm to -8 dBm A fixed value / over -3 dBm
BH +7 dBm to -18 dBm A fixed value / over +6 dBm
CH +10 dBm to -15 dBm A fixed value / over -13 dBm

Table 2-1 Frequency Range and Levels

Page 28

2.1 Overview

The network analyzer consists of five blocks:

  • 1. Source Block
  • 2. Receiver Block
  • 3. Front-end Block
  • 4. Front Panel Block
  • 5. Digital Block

See Figure 2-1 below.

Figure 2-1 Simplified Block Diagram

Page 29

2.2 Basic Theory

The source block generates the synthesized RF signal. The generated signal is supplied to a DUT through the front-end block to measure the forward/reverse characteristics. After the signal has passed the DUT, the signal returns to the receiver block through the Front end block. In the receiver block, the signal is converted to a low frequency and passes to the digital block. The passed signal is converted to the digital signal by the A/D converter in the digital block. The digital signal is calculated to obtain the amplitude, phase characteristics and the group delay time, forward/reverse characteristics. The result are displayed on the front panel block.

2.2.1 Source Block

The source block consists of the synthesizer, PLL, source, 4.44 GHz DRO, YTO, coupler modules.

The synthesized source module provides an RF signal which is generated by mixing the 4.44 GHz DRO module with the 4.4 GHz to 8.2 GHz YTO module.

For the R3766AH/BH/CH or R3767AH/BH/CH an additional frequency range of 3.8 GHz to 8.0 GHz is available, using the synthesized YTO module.

Figure 2-2 Source Block Diagram

Page 30

2.2.2 Receiver Block

The receiver block consists of three input modules and one PG module. The input modules are referred to as Ach, Bch and Rch. The Rch input module is connected to the coupler module internally. The other two INPUT modules, Ach and Bch, are connected to the Front-end block.

The 820 kHz signal is generated by sampling the applied signal through a DUT and the signal from the PG module. The 820 kHz signal is referred to as 1st-IF.

Then the 20 kHz signal, which is referred to as the 2nd-IF, is generated by mixing the 1st-IF with the signal from the synthesizer module (in the source block). 2nd-IF is then sent to the A/D converter for further analysis.

Figure 2-3 Receiver Block

Page 31

2.2.3 Front-end Block

The front-end block consists of the bridge and SW modules. The number of the bridge module depends on the types.

R3764/65/66/67AH

These network analyzers have SOURCE, A PORT and B PORT connectors. The SOURCE connector is directly connected to the source block. The A PORT and B PORT are directly connected to the Ach and Bch input modules in the receiver block.

R3764/65/66/67BH

These network analyzers have TEST PORT 1 and TEST PORT 2 connectors. The TEST PORT 1 connector is connected to the source block through the bridge module to measure the reverse characteristics by connecting to the Ach input module. The TEST PORT 2 is directly connected to the Bch input module.

R3764/65/66/67CH

These network analyzer have TEST PORT 1 and TEST PORT 2 connectors. The TEST PORT 1 is connected to the source block through the bridge and SW modules. The SW module switches the generated signal to supply the signals to DUT. Also The bridge modules are connected between the each ports and the SW module. The connected bridge module to TEST PORT 2 measures the reverse characteristics by the Bch input. See Figure 2-4.

Figure 2-4 Front-end Block Diagram

Page 32

2.2.4 Digital Block

The digital block consists of the A/D converter and CPU modules. The CPU module consists of the 32-bit high performance CPU, a special CPU, DSP and so on.

The digital block controls the source, receiver, front-end and the front panel blocks. They provide mathprocessing functions, as well as communications between the analyzer and the external controller. Data processing from the A/D converter is performed by the DSP and 32-bit high performance CPU and the internal Basic program can be run from this CPU. For the convenience of Basic programmers, an external IBM PC/AT keyboard and VGA monitor can be connected. The front panel block is controlled by the special CPU. See Figure 2-5.

Figure 2-5 Digital Block Diagram

Page 33

2.2.5 Front Panel Block

The front panel block consists of the key-pad and display modules. The key-pad module contains the encoder for convenience to move a marker. For the R3765AH/BH/CH or R3767AH/BH/CH the display module uses the 7.8-inch color TFT LCD module. For the R3764AH/BH/CH or R3766AH/BH/CH the display module uses the VGD module.

The display and the key-pad modules are controlled by the digital block for the user. See Figure 2-6.
