The 34980A Switch/Measure System masters switching, measurement, and control features by offering a superior selection of switch topologies and system control features. A state-of-the-art DMM has been integrated into the 34980A mainframe providing a wide variety of measure capability. The 34980A mainframe also includes standard PC connections and instrument control options for your ease of use. Discover the detailed advantages of upgrading your test system using the 34980A in this document. How your 3499A/B/C Test System Benefits From Upgrading to the New 34980A Switch/Measure/Control System Application Note 34980A Mainframe, plug-in modules and terminal cards Measurements One of the advantages of the new 34980A is its ability to make highly accurate test system measurements. The integration of a high-speed DMM into the mainframe enhances the 34980A switch and control system by providing voltage, current, temperature, frequency, and resistance measurements without using any of the mainframe’s available eight slots. The DMM conveniently generates measurement results in selectable engineering units. Eleven different types of measurements can be made and are listed on the page 2. The 34980A time-stamped measurement data can be stored or displayed and analyzed as the measurements are acquired. The 34980A also has configurable High/Low limits on each channel that activate an alarm if the input signals are out of the set range. The 34980A’s integrated DMM saves you time and money by reducing the number of individual instruments required, and additional cabling for measurements and triggering. In comparison, the 3499A/B/C switch requires an external DMM or other measurement instrument as well as additional wiring to provide the same functionality. List of 34980A Measurement Capabilities • Temperature measured with Thermocouples, RTDs and Thermistors • DC and AC volts • 2- and 4-wire Resistance • Frequency and Period • DC and AC current • 4 alarms for High/Low or both limits for each channel • Digital I/O • Analog outputs (DAC) The 34980A mainframe also includes four 2-wire internal analog buses. This is a differentiating 34980A feature and not included with the 3499A/B/C. The analog buses can be used to route measurements directly to the internal DMM or connect the mainframe modules to external instruments. The analog bus can be used to extend modules such as the matrix switch modules, or provide additional signal routing between modules. Mainframes The 34980A Multifunction Switch/Measure Unit consists of an eight-slot mainframe with an optional DMM. The DMM is mounted directly behind the front panel so it does not require any of the available eight module slots. A choice from 19 different modules can be plugged directly into the eight-slot mainframe. In comparison, the 3499 Family has mainframes in three different sizes: A, B, and C that house five, two, and nine modules respectively. The 3499 Family offers a selection of 30 plug-in modules, 13 of which are the earlier generation HP 3488A Switch/Control Unit modules. Since some of the modules were designed for the 3488, and some modules specifically for the 3499, there is duplicate functionality between the modules. As test systems and capability needs expand there is a call for a greater number of switch channels within one system. The 34980A switch modules are designed for high switching channel count. The 34980A eight- slot mainframe fully loaded with 2-wire multiplexer modules houses a total switch channel count of 560. The 3499C nine-slot mainframe fully loaded with 2wire multiplexer modules houses a total of 360 switch channels. For a quick summary of the maximum switch channel count for the switch systems mainframes, see Table 1. 3499C Full Rack, 5U 9 (electrical)/ 360 14 (physical) Table 1. Max 2-wire Mux channel count per Mainframe Mainframe Mainframe Size Number of Module Slots Maximum Number of Channels (2-wire) 34980A Full Rack, 3U 8 560 3499B Rack, 2U 2 80 3499A Half Rack, 2U 5 200 Modules The 34980A implements a superior selection of switch topologies. The 34980A switch topologies are similar to 3499A/B/C switch modules and include multiplexers, matrixes, high-power, general purpose, and RF/microwave switches. However, the 34980A modules have utilized the newest switch technology which enables a higher density of channels per module, and the ability to achieve the faster scan rates with the integrated DMM. The 34980A offers other functionality used in test systems and includes digital I/O, a counter/totalizer and D/A converters. New 34980A functions include a FET multiplexer switch module, a counter/timer and digital I/O with pattern generator/detector along with digital I/O and D/A converters. The 34980A RF and microwave switch drivers offer functionality for a broader range of RF/microwave switches being used by customers today. The 3499A/B/C does provide a selection of optics switching which is not available with the 34980A. Table 2 shows the 349...
