8922A Section 1 Introduction & Specifications 1-1. INTRODUCTION 1-2. The Model 8922A is a Digital True RMS Voltmeter, capable of accurately measuring the true rms value of nonsinusoidal signals containing AC or AC + DC components. The instrument has a frequency range of IO Hz to 11 MHz with a full-scale crest factor of seven, and is capable of displaying measurements in either volts or dB units. 1-3.
PAGE 10
8922A 1-8. The PTI (Portable Test Instrument) case is a family of injection molded, plastic instrument packages of various sizes which may be stacked vertically and latched together to form portable test stations. When instruments are stacked the weight of the stack should be limited to 40 pounds total, and the instrument drawing the most power should be on the top. Stacked_ jnstruror.-nts have a horizontal air space between them to reduce heat conduction between instruments. 1-9. SPECIFICATIONS 1-10.

@ static awa rene ss A Message From 9 Fluke Corporation Some semiconductors and custom IC's can be damaged by electrostatic discharge during handling. This notice explains how you can minimize the chances of destroying such devices by: 1. Knowing that there is a problem. 2. Leaning the guidelines for handling them. 3. Using the procedures, packaging, and bench techniques that are recommended. The following practices should be followed to minimize damage to S.S. (static sensitive) devices. 1.
PAGE 16
5. USE STATIC SHIELDING CONTAINERS FOR HANDLING AND TRANSPORT. 8. WHEN REMOVING PLUG-IN ASSEMBLIES HANDLE ONLY BY NON-CONDUCTIVE EDGES AND NEVER TOUCH OPEN EDGE CONNECTOR EXCEPT AT STATIC-FREE WORK STATION. PLACING SHORTING STRIPS ON EDGE CONNECTOR HELPS PROTECT INSTALLED S.S. DEVICES. 6. DO NOT SLIDE S.S. DEVICES OVER ANY SURFACE. 9. HANDLE S.S. DEVICES ONLY AT A STATIC-FREE WORK STATION. 10. ONLY ANTI-STATIC TYPE SOLDERSUCKERS SHOULD BE USED. 11. ONLY GROUNDED-TIP SOLDERING IRONS SHOULD BE USED. 7.

8922A COMMON MODE VOLTAGE MEASUREME NTS enough isolation to prevent ground loop currents and, therefore, measurement errors due to ground loops. 2-34. 2-28. When you connect the low input of the 8922A to a potential greater than 400 mV above power ground, the diode pair conducts and effectively clamps the input common mode voltage. 2-3S. The 8922A will accomodate common mode voltages as high as 600 m V peak, usually enough to eliminate ground loops in the power connections.

8922A proportionally as the input goes down-scale. Use the following formula to calculate the crest factor of signals less than full-scale: 7 (Range) Input Level For example, given the DMM is at the 20V range with a lOV input: required for good performance below IO Hz. This additional damping may also aid in the measurement of higher frequency signals when the level of the signal fluctuates.

8922A mode will not affect any previous reference established in the dB display mode (see following paragraphs for additional information about establishing a dB reference). NOTE The dBm REFERENCE switch does not affect the fixed JO MO input impedance ofthe 8922A. All impedance matching terminations must be added externally by the operator. dB Display Mode 2-53. 2-54.

Typical Relative dB Measurements 3. Depress the dB/VOLTS switch (in). 4. Depress the REL/ dBm switch (in). This establishes the voltage (V) as the 0 dB reference level. Therefore, subsequent dB measurements will be equivalent to dBm measurements as long as the system impedance R is maintained.

8922A Section 3 Theory of Operation 3-1. 3-5. INTRODUCTION 3-2. The information in this section describes the theory of operation for the 8922A True RMS Voltmeter. The theory has been divided into two major headings; overall functional description and detailed block diagram description. To gain maximum benefit from this section, we recommend that you read each paragraph in the order presented while referring to the associated figure or the appropriate schematic in Section 8. 3-3.

8922A 3-8. The signal conditioner insures that the varying levels of instrument input voltages are properly scaled before being applied to the rms converter. The rms converter works on a thermal sensing principle. Basically, it operates by balancing the heating power of a de feedback signal to the heating power of the ac input signal.

Overload conditions would result during turn on, turn off, or any time therms value of the applied input exceeds the operating range of the sensor. 3-20. A/D Converter 3-21.

8922A Table 3-3. Output Range Codes 3-32. DATA LINES RANGE dB Computations 3-33. If the 'dB/VOLTS switch is in the dB position, a non-linear count of the clock pulses is enabled. The binary rate multiplier (RM) passes only a fraction of the clock pulses on to the controller's main counter (see the illustrated input to the main counter on Figure 3-7). This count approximates the logarithmic curve of the dB scale and, like the VOLTS mode, is stored in the data latches.
PAGE 34
8922A reference measurement the controller must use an initial reading, and to obtain an initial reading it must use a reference impedance. Therefore, before the REL mode can be selected the controller must be allowed to make at least one complete measurement while in the dBm mode. Once the measurement has been completed the REL mode may be selected. The reading will now be fed back to the reference latches and held.

The Y2014 allows one instrument to be offset-mounted on the right side in a 19inch equipment rack (Figure 600-1). The Y2015 allows two instruments to be mounted side-by-side in a 19-inch equipment rack (Figure 600-2). The Y2020 allows one instrument to be panel mounted in a DIN size opening.

8922A -003 Option Counter Output 603-1. INTRODUCTION 603-2. The -003 Counter Output Option converts an rms input signal into an isolated 100 m V peak, squarewave suitable for triggering a counter. There are several advantages as opposed to using separate inputs for the DVM and the counter. First, the 8922A autoranged input has a much greater dynamic range than a counter.

8922A -004 Option Logarithmic Analog Output 604-1. INTRODUCT ION 604-2. The Logarithmic Analog Output Option provides a non-isolated output voltage which varies continuously as the logarithm of therms input. Scaling is: OV de output corresponds to 0 dB which is 200 µV rms input to the 8922A while 13. l V de output = 131 dB = 700V rms input. A continuous frequency response of circuits with a wide dynamic output is easily plotted on an XY recorder using this option. The option's output is non-isolated.
