Measurements are made in a fully differential input mode up to 250V. Ranges include 0.2V, 0.6V, 2V, 6V, 10V, 20V, 60V, 200V and 600V (rated to 250V) and auto-range.
The System has three DC voltage signal sources, each of which can source up from ±10V, and providing up to 10mA of current. These sources are internally sensed.
System provides two 100mA current sources with programmable voltage. Each source can be programmed to a compliance voltage between ±12V. When used together, the sources can provide up to 24V differentially.
AC Voltage Measurement up to 250VRMS
These true RMS measurements are provided with AC or AC+DC coupling. Ranges include 0.2V, 0.6V, 2V, 6V, 20V, 60V, 200V, 600V (rated to 250V) and auto-range.
Frequency Measurements
Frequency measurements can be made from DC to 10MHz. Higher frequencies can be performed if the test fixture includes a pre-scaler. The ground-referenced input can be from 300mV to 5V, and can be AC or DC coupled. The trigger level can be set in the range of ±2.2V.
Sine Wave & Square Wave
The System can provide sine wave output in the range of 100mV to 20Vp-p (7VRMS). The frequency selection range is 1Hz to 50KHz. Sine wave output is ground referenced and can provide up to 10mA of output.
The System can provide square wave output. Amplitude can be ground-reference to ±10V, or can be between two programmable amplitudes each from ±10V, with up to 10mA. The frequency selection range is 1Hz to 50KHz.
Digital I/O
The standard configuration of the Analyst ems+ft includes 96 digital I/O pins. These pins can be relay-connected to the UUT in byte increments. Within each byte, each pin can be set to be an input (tri-state output) or an output. Since each pin has a 10K ohm pull-up (in conjunction with totem-pole outputs), it is compatible with most logic families. Logic high output can be selected to be +5V or +3.3V.
Period Measurements
Period measurements can be made from 12.8 milliseconds to 128 seconds. The ground-referenced input can be from 300mV to 5V, and can be AC or DC coupled. The trigger level can be set in the range of ±2.2V, and can be set to respond to rising or falling transitions. Period measurements can be made with A and/or B inputs.
Counts
Counts can be made of up to 65,535 events based on the trigger event occurring. The ground-referenced trigger input can be from 300mV to 5V, and can be AC or DC coupled. The trigger level can be set in the range of ±2.2V, and can be set to respond to rising or falling transitions. Up to 5MHz signals can be counted.
Parallel Functional Test Technology is patent pending.
