Programmable Frequency Counter

Información

Introduction Your PM6685 Counter is designed to bring you a new dimension to portable and bench-top counting. It offers significantly increased performance compared to traditional counters. The Counter offers the following advantages: - Ten digits of frequency resolution per second and 250 ps resolution, as a result of high-resolution interpolating reciprocal counting - A 2.7 GHz input frequency option - A foolproof auto trigger function New powerful and versatile functions The unique versatile auto sensitivity and auto waveform compensation takes care of all triggering from 50 Hz and up. It even optimizes itself to the requirements of different measuring functions. Another unique feature in your instrument is the bar-graph level monitor. It always shows you the input signal level on a dB scale to verify proper signal strength. The burst frequency and PRF functions measure bursts and AM signals without any external synchronization signal. To solve even tougher tasks, the Counter has complete arming possibilities which lets you synchronize measurements with external events. You can even delay the arming of the Counter (compare to delayed time base triggering in an oscilloscope). Read more about Arming in Chapter 7, "Measurement Control”. No mistakes You will soon find that your new Counter is a delight to operate. One example is the back light LCD that shows you measurement results, setting status, and operator messages. The AUTO function triggers automatically on any input wave form. A bus-ieam mode simplifies GPIB programming. With bus-leam mode, manual Counter settings can be transferred to the controller for later reprogramming, There is no need to learn code and syntax for each individual Counter setting if you are an occasional bus user.

This is a complementary service manual covering instruments with manufacturing numbers exceeding 840684. The principal differences are to be found in Chapter 7 and in Chapter 8 due to a major redesign of the main PCB. Do not dispose of the previous edition, identified by the part number, 4822 872 25012, and the publishing date, June 1996. You may have to refer to it for information on older instruments as well as options not mentioned here. 1 Safety Instructions 2 Performance Check General Information ... 2-2 Recommended Test Equipment ... 2-2 Front Panel Controls ... 2-2 Short Form Specification Test ... 2-3 Rear Input/Output ... 2-4 Measuring Functions ... 2-4 Options ... 2-5 3 Disassembly Removing the Cover ... 3-2 Reinstalling the Cover ... 3-2 PM9624 (HF Input) ... 3-2 PM9626B (GPIB Interface) ... 3-3 PM9691 or PM9692 (Oven Oscillator) ... 3-3 4 Circuit Descriptions Block Diagram Description ... 4-2 General ... 4-2 Hardware Functional Description ... 4-4 Front Unit ... 4-4 Main Board ... 4-5 Rear Panel Unit ... 4-13 Optional Units ... 4-14 Software Functional Description ... 4-15 Test Routines ... 4-16 5 Repair Preventive Maintenance ... 5-2 Calibration ... 5-2 When to Replace the Fan /PM6685R only ) ... 5-3 Troubleshooting ... 5-4 General ... 5-4 Safety Inspection and Test After Repair ... 5-9 General Directives ... 5-9 6 Calibration Adjustments Introduction ... 6-2 Preparation ... 6-2 Power supply ... 6-2 Input Amplifier ... 6-3 Reference Oscillators ... 6-4 Other Options ... 6-6 7 Replacement Parts Introduction ... 7-2 Mechanical Parts ... 7-3 Main Board ... 7-6 Front Board ... 7-12 GPIB Interface (PM9626B) ... 7-13 8 Drawings & Diagrams How to read the diagrams ... 8-2 9 Appendix How to Replace Surface Mounted Devices ... 9-2 Electrostatic discharge ... 9-3 Glossary ... 9-4 Power supply Switchmode Module ... 9-5 Circuit Descriptions ... 9-5 Repair ... 9-6 Calibration Adjustments ... 9-7 Replacement Parts ... 9-8 PM6685R ... 9-12 Introduction ... 9-12 Performance Check ... 9-12 Functional Description ... 9-12 Calibration Adjustments ... 9-13 Replacement Parts ... 9-14

Programming Manual You should use this ProgrammingManual together with thePM6680B/1/5 Operators Manual. That manual contains specificationsfor the Counter and explanations of the possibilities and limitations of the different measuring functions. Sections The chapters in this manual are di- vided into three sections aimed at dif- ferent levels of reader knowledge. The ‘General’ Section, which can be disregarded by the users who know the IEEE-488 and SCPI standards: – Chapter 2 Bus Commands for the Benchtop User gives bus com- mands for the front panel keys. – Chapter 3 Introduction to SCPI explains syntax data formats, sta- tus reporting, etc. The Practical Section of this manualcontains: – Chapter 4, Programming Exam- ples, with examples of typical pro- grams for a wide variety of appli- cations. These programs are writ- ten in GW-basic and C. This Manual The ‘Programmers Reference’ Sec- tion of this manual contains: – Chapter 5, Instrument Model ex- plains how the instrument looks from the bus. This instrument is not quite the same as the one used from the front panel. – Chapter 6 Using the Subsystems explains more about each subsys- tem. – Chapter 7, How to Measure Fast is a set of measuring situations which the user is often confronted with when programming a Counter. This chapter also contains infor- mation about how to use the more complex subsystem. – Chapter 8, Error Messages con- tains a list of all error messages that can be generated during bus control. – Chapter 9, Command Reference, This chapter gives complete infor- mation on all commands. The sub- systems and commands are sorted alphabetically.
