Similar in function to the V420, the P620 features six independent, isolated channels that can simulate platinum RTDs and resistances ranging from 5 ohms to 5Mohms. It is intended for system-level testing of process control systems, FADEC engine controllers, and other critical systems. The P620 uses entirely solid-state simulation to eliminate transient errors associated with relay switching and provides for monotonic resistance changes. It also features built-in self-test and easy remote calibration check.
The T840 is a dual-channel high-voltage pulse generator. It is suited to driving PLZT piezoelectric or electro-optical devices, microchannel/PMT gating, beam deflection, time-of-flight mass spectrometers, and semiconductor test. Each channel is programmable for 0 to +1200 volt pulse output, and DC offset is available up to 400 volts.
The D200 bridges the gap between Highland Technology's picosecond domain T160/T165 butterfly laser drivers, and the D100 microsecond domain bar laser driver. Maximum flexibility is obtained through the combination of high drive-current capability, fast edge-speeds, and wide operational pulse width ranges. An adjustable constant-current source, DC-coupled signal path, and logic follower mode, enable full duty CW operation. 12V DC operation and remote control capability facilitate nanosecond laser integration in embedded scientific, industrial, and commercial applications.
The P470 features 8 isolated channels, each capable of two modes of simulation: J K E T R S B and N thermocouple types, or output voltage simulation in a range of ± 100 millivolts. Two non-isolated precision RTD signal conditioners are provided for reference junction temperature sensing, plus one on board reference junction sensor. Its built-in self-test feature allows quick user verification of module functionality and easy remote calibration check. Control is via text commands or through the internal web page server, making only access to a web browser necessary to exercise all P470 functions.
Gated/Triggered oscillators are precision clock oscillators that start instantly when an external gate signal is received. The first logic-level output edge begins nanoseconds after the trigger, and is followed by uniformly spaced clock edges. The oscillators completely recover, and can be restarted, in four clock periods or less. Optional crystal oscillators or external frequency references allow arbitrary precision yet maintain instant-on trigger coherence.
The V410 is a 6U VME module that provides sixteen independent analog inputs that may be used to read RTDs, thermistors, and other similar resistive sensors. It can also read cryogenic diodes. Users may set input range and adjust other settings at VMEbus speed, and depending on the range selected the microprocessor will do the necessary calculations and output voltage, resistance, or temperature. Temperature conversion is available for 100Ω and 1000Ω, series 385 and 392, platinum RTDs.
The V280 includes 48 isolated logic inputs. It is available in versions for nominal 5 volt or 24 volt input levels. The V280 has independently programmable rising and falling edge response times to support contact debounce, glitch catching, and DC or AC inputs.
The D100 is a constant-current pulsed laser driver capable of driving bar laser stacks or VCSEL arrays up to 250 amps and 30 volts. Current and pulse width can be set by on-board trimpots or user-provided signals. The D100 provides user-settable peak current and pulse width limiting circuits for laser protection, and thermal/SOAR protections for the onboard power semiconductors.
The T680 contains five wide-range time stampers. Each channel can snapshot the time of the rising edge of one electrical input, to 12.2 picosecond resolution with 48 bit range. In time-stamp mode, individual time stamps may be read. In TIC mode, channel 0 may be used as the "start" time reference for channels 1-4, with the option to acquire times after or before/after the start event.
The V120/V124 are VME/VXI bus master crate controllers, usable as crate slot 0 arbiters or as secondary controllers. They allow a PCI Express host system to control a VME/VXI crate, allowing customers to take advantage of the widely available VME I/O infrastructure without the difficulties of running a separate single-board computer.
