USBTMS Support
USBTMC stands for USB Test & Measurement Class. Any USB device conforms to USBTMC without the limitations of operation systems and environment can work under VISA assistance, and communicate with a computer. In other words, the control procedures via VISA to USBTMC device and via VISA to GPIB device are the same.
The advantage of using USBTMC with M3500A is that you don't have to buy any expensive GPIB module, and waste time to re-program the previous application software which is for GPIB. Only the instruments conform to USBTMC protocol in the VISA basis, and the version of NI-VISA 3.1 or upward driver is installed. The USBTMC unit under the original GPIB software will be recognized, and can be easily used. Besides, it also offers users other benefits, for example, support 127 DMM connections at a time, USB cord can work with a long distance application (at most 30M), and it is easy to get the cord.

High Speed - 2000 Readings / Sec - The M3500A is engineered with expertise to reach such a high performance: both of the sampling rate and the data transfer rate can achieve 2000 readings per second.
19 Full-Featured Functions - There are 11measurements and 8 math functions : DCI, DCV, ACI, ACV, 2WΩ, 4WΩ, Frequency, Period, Diode Test, Continuity, Temperature, Limits, Ratio, MX+B, %, dB, dBm, Min/Max, and Null. In addition, Trigger and Memory functions are also involved. All functions above facilitate your measurement applications better.
Temperature Measurements - Our thermal measurement function supports two types of measurements: thermocouples and RTDs. For thermocouples, we support up to seven types of sensors: J, K, T, E, N, S and R, using a NIST Monograph 175 reference table. Moreover, for the RTDs temperature conversions, we adopt three types of standard: ITS-90, IEC751 and Callendar-Van Dusen standard in our thermal measurement functions. All these are made for user's convenience.
Multi-Point Scan - The M3500A supports up to 10 channels (2-pole) multi-point scan. For using this option, user needs to have an additional multi-point scanner card (Model M3500-opt01) The installation of the multi-point scanner card is very easy - just turn the power off and plug in the multi-point scanner card, and it is done!
Dual Displays with 3-Color Annunciators - This model comes with a unique 5x7 dot matrix, VFD dual displays with three-color annunciators. User can easily distinguish each symbols by their colors.
Noise Immunity - This model has an excellent performance on noise immunity. The core of this DMM is a powerful multi-slope analog to digital converter (A/D converter) This special A/D converter (p.s. patent is pending) helps the DMM to reach high-speed sampling rate, filters out most noise, and still keeps a good measurement linearity. In addition, to reduce the environmental background noise, we have added four sets of earth ground on the meter's front panel. And the copper conductors inside the meter also contribute to reducing thermal EMFs.
Built-in USB Interface - The M3500A Series is equipped with a standard USB interface. This easy-to-use and hot plug-in USB interface has a high data-transfer rate over 2000 readings per second. It allows your DMM to reach a truly high speed, both internal sampling rate and I/O data rate, thus increase the measurement speed of your DMM. A GPIB interface is optional available !
Easy & Free PC Applications - We provide MatLab® and LabView® applications that allows user to do a variety of tasks. Also feature the PT-tool that can acquire date directly from the measurement into MS word® or Excel®. Even without MS Word® or Excel®, user can choose our PT-Link which is a stand-alone application => Examples & Dowbloads !

Picotest M3500A + M3511A - High-Performance DMM
The M3510A and M3511A 6 1/2 Digits Multimeters are the newest generation of DMMs from Picotest. These new DMMs offer compact size, light weight, fast measurement speed & throughput, expanded measurement functions, systematization capability and highly usable interfaces including a standard USB interface and an optional GPIB/RS-232 interface. The M3510A and M3511A DMMs are suitable for both production and research/development use.
M3510A and M3511A adopt the latest A/D technology and achieve 50,000 readings per second at 4 1/2 digits. When sending data to your computer, M3510A and M3511A can achieve high precision and stability compared to other DMMs with slow data transmission rate. With M3510A and M3511A, your work efficiency will be greatly improved, and the operational cost will also be greatly reduced.
The dual measurement display feature of M3510A and M3511A offers two measurement results displayed at the same time and it is easy to set up and configure. For example, when measuring DCV, you may also conduct Thermocouple measurement on M3510A. This allows you to observe temperature change while making other measurements. M3510A can function as a multimeter and a thermometer in one.
The M3510A and M3511A DMMs support the RTD temperature measurement and support the standards such as ITS-90, IEC751 and Callendar-Van Dusen. The RTD function is recommended for more precise measurement. M3510A also provides the Thermocouple (TC) function. It has a built-in cold junction compensator for improved TC accuracy. Without additional plug-in's and reference temperature settings, you can measure temperature directly via Thermocouples of K, J, R, S, T, E, N, C and B types.
The M3510A and M3511A DMMs offer the capacitance measurement and dual measurement display, in addition to standard measurements, such as DCV, DCI, ACV, ACI, 2WΩ, 4WΩ, Frequency, Period, Thermocouple & RTD, and the math functions, such as Limits, Ratio, MX+B, %, dBm, dB, Min/Max & Null. Measurement ranges have also been expanded. For instance, DC and AC Current Ranges now go up to 10 A.
The M3510A and M3511A DMMs adopt an analog conversion technique to provide true RMS value for ACV/ACI measurements regardless of the waveform shape. Only the “heating value” of the AC components of the input waveform is measured. For non-symmetrical waveforms, such as pulse trains, the DC components will be rejected by the RMS measurement.
Configuring M3510A and M3511A is straightforward. Unlike other DMMs with complicated operation modes in the configuration menu, M3510A and M3511A offer easy-to-use SHIFT, CONFIG, ENTER buttons, arrow keys and corresponding softkeys at the lower part of the display across all the measurement configurations. Using equipments from Picotest just gets easier than ever.
