The V450 16-channel VME analog-to-digital converter can acquire both a wide range of DC voltages and thermocouple measurements for all major thermocouple types. Each fully isolated channel can be configured independently, and arbitrary sets of channels can be synchronized for true simultaneous data acquisition. In voltage mode, each channel of the V450 acts as a floating voltmeter, with 24-bit resolution over voltage ranges from ±25mV to ±250V. RMS noise is less than 5 PPM for most ranges at the 4 Hz sample rate, with 50/60Hz rejection of better than 80dB. In thermocouple mode, channels can measure thermocouples of types J K E T R S B and N, and resolve temperatures to 1/16°C. Any of four platinum RTD inputs may be used to sense an external reference junction, or an onboard temperature sensor can allow direct connection to the front panel inputs. Any combination of channels can be assigned to any voltage or thermocouple range, and voltage and thermocouple measurements can be mixed freely. Channels also feature programmable sampling rates up to 500Hz, switchable open input detection, and overvoltage protection to 350V regardless of configuration. Thermocouple loop resistance may be measured by user command; subsequent measurements are automatically compensated for burnout current errors without the error normally associated with open-thermocouple sensing.

With a scant 25ns insertion delay, the P400 can be used in lab setups with tight tolerances. The four channels can be independently controlled as delay / width or leading / trailing edge pulses. The P400 allows a trigger rate of up to 10MHz. Those requiring an extremely low jitter rate can select the optional ovenized crystal oscillator. The onboard help system is always available at the touch of a button. Each button, input, output, and setting is explained. Using the help system, any user will be able to become quickly proficient with the P400 and its many features. The spinner knob and navigation buttons make controlling the P400 simple and intuitive. One of the most exciting new features of the P400 DDG is the optional Ethernet interface. Using a pre-existing Ethernet network, a user can control the P400 from across the bench or across the world. Setup involves merely plugging in an Ethernet cable to the back panel. The IP address can be set manually or automatically via a DHCP server.

July 2003 Highland Technology, Inc., announced the release of Model V375 4-Channel VME Arbitrary Waveform Generator. The V375 builds on the success of its predecessor, the Model V370, by extending the output bandwidth to 300 kHz and adding four inputs for user waveforms to sum into the channel outputs. A new burst mode allows software or external input to trigger generation of one or more waveform cycles. Our VME arbs form the foundation of multi-million dollar test programs at major aircraft engine and power systems manufacturers. The V375 is a direct result of customer requests for new features to support their new product development. The V375 is designed with features that make it ideal for simulating sensor signals from complex rotating machines. An onboard microprocessor executes macro commands that simplify generation of pure and distorted polyphase AC waveforms, with amplitude, frequency, phase, and distortion components smoothly variable in real time. Other macros create complex pulse trains with real time control of pulse positions, amplitudes, and missing pulses. The module provides four memory-table waveform generators with 16-bit amplitude resolution and from 64 to 65,536 points per waveform. Four independent direct digital synthesizer (DDS) frequency sources step through the memory table at rates up to 15 MHz. The DDS frequencies are variable in real time in milli-Hertz increments, and per-channel divisors allow simulation of fractional "gear-ratio" waveforms. A synchronization capability links up to 64 channels across multiple modules. Each channel output features an analog summing stage that can mix up to four generated waveforms plus one user waveform per channel. And, a programmable gain stage on each output allows the user to dynamically scale the output waveform amplitude without reloading the memory table.
