- 2. 2 A/D converter Photo coupler A/D converter LOGIC CPU Ach Bch Hi Lo Hi Lo A new concept digital multimeter 7352 series has ap- peared, offering various applications and improved throughput. The 7352A/7352E is the next-generation digital multi- meter having twin-A/D converters that enable fully-inde- pendent measurement of two-channel signals, and is suit- able for high-speed measurement, parallel measurement of different functions and multi-channel measurement by configuring a system. The channel A (Ach) has basic measurement functions for DC voltage/current, AC voltage/current, resistance and frequency, while the channel B (Bch) has DC volt- age/current, AC current and temperature measurement functions. Thus, higher throughput can be obtained with Ach/Bch synchronous measurement or Ach/Bch parallel measurement of different functions. Furthermore, the dynamic range of current measurement has been broadened significantly, enabling measurement from low current of 10pA to high current of 10A. The 7352A is equipped with an RS-232 interface in ad- dition to USB and GPIB interfaces for use in R&D and production lines. The 7352E is equipped with a USB in- terface for low-cost system configuration. The remote command language not only complies with the conventional ADC commands and SCPI, but also is compatible with that of the digital multimeter R6452A. Conventional dual DMM 7352A/E Ach Bch Hi Lo Hi Lo 5MΩ 5MΩ A/D converter LOGIC CPU Photo coupler Photo coupler Two-in-one TWO Evolution from Dual to TWIN ● Measures Ach and Bch alternately with a single A/D converter. ● The impedance between Ach and Bch is only 5MW because Bch is a differential input circuit. The potential difference between the channels due to a differential resistance error causes a large error in Bch measurement. (0.05%) ● Synchronous measurement by twin A/D converters ● Completely isolated between the channels Open up a new age of digital multimeters by real two-channel synchronous measurement
- 3. 3 Twin A/D converters realize synchronous measurement of Ach and Bch functions. Even at the sampling rate per PLC at which noise rejection is possible, two-function measurement data can be obtained without switching the functions, allowing the significant im- provement of the system throughput. In building up a system, system interfaces are available for easy connection with a programmable controller. The 7352A is equipped with USB, GPIB and RS-232 interfaces as standard. Since Bch is fully independent from Ach, its measurement is not affected by the potential difference between them. In addition, high-accuracy Bch measurement is available with 5½-digit display. Moreover, this series is capable of high-accuracy parallel measurement of different measurement functions such as voltage/current, voltage or current/temperature, or AC/DC be- tween Ach and Bch. The broadened dynamic range enables measurement of low power consumption. Ach has measurement ranges from 2µA (10pA resolution) to 2A, and Bch has 10A measurement range (100µA resolution). Two functions such as current/voltage or current/temperature can be measured with high sensitivity and resolution and these results are dual-displayed.

Thus, in such measurement, two digital multimeters are required. On the other hand, the 7352A/7352E is provided with com- pletely isolated Ach, Bch and TEMP, and is equipped with two independent A/D converters. Thus, switching measurement and functional change are unnecessary, and high-throughput measurement is available without influence between the channels. It has six measurement capabilities: AC input volt- age/current and frequency on Ach, DC output voltage/current on Bch, and temperature on rear TEMP. Applications The input and output characteristics, load regulation character- istics, conversion efficiency, and rise in temperature of a DC/DC converter can be evaluated by a single unit of the 7352A/7352E. This series has five measurement capabilities: input voltage/cur- rent on Ach, output voltage/current on Bch and temperature on rear TEMP. In addition, change in input current or temperature against load current fluctuation can be measured in real time by using two-channel parallel measurement. Thanks to complete isolation between the channels, the input and output of an isolated DC/DC converter can be measured by just one unit. The channel outputs of a multi-output converter can be also monitored simultaneously by using one unit per two channels. Even in such case, there is no crosstalk between the channels.
