Virtual Instrument Platform

zoom

This unit uses up-to-date technology combined with Windows-based programming to integrate a full set of virtual instruments into one self-contained unit. The unit is controlled by a PC through a USB port.

A complete set of virtual instruments is integrated into the VIP unit. These run on the student's PC and provide virtual multimeters, oscilloscope with spectrum-analyzer mode and function-generator as they follow the on-screen learning material. A virtual data logger which can capture any combination of oscilloscope and multimeter inputs is provided, together with a grapher application.

The following facilities are provided on-board:

Two built-in virtual multimeters, each providing:

• Fully-separate meters with floating inputs.
• 2mm socket connections.
• Digital or Analog meter display.
• Auto or Manual range selection.
• Voltage ranges 60V, 20V, 2V, 200mV.
• Current ranges 2A, 200mA, 20mA, 2mA, 200µA.
• Resistance ranges 20MΩ, 2MΩ, 200kΩ, 20kΩ, 2kΩ, 200Ω.
• Continuity range with audible buzzer.
• Diode test range.
• Overvoltage and overcurrent protection.
• Copy and paste of meter display.
• Realistic on-screen virtual instrument.

One built-in virtual oscilloscope with spectrum analyzer mode, providing:

• Two channels at up to 20MHz sampling rate.
• >1MHz –3db input bandwidth.
• Analog and Logic noise filters.
• 1MΩ // 30pF input impedance.
• BNC sockets for standard x1/x10 probes.
• 2mm sockets for direct connection to D3000 boards.
• DC, AC or GND input coupling.
• Voltage ranges 5mV/div to 20V/div.
• Invert and 1+2 modes.
• Timebase ranges 0.5µs/div to 1s/div.
• Rollover mode on slow sweep ranges
• Timebase Off and X-Y display modes.
• Trigger on Auto, Channel 1, Channel 2 or External Trigger.
• Cursors for voltage, time and frequency measurement.
• Spectrum Analyzer mode on both channels, with linear or dB scale
• Storage and recall of waveforms on the PC
• Copy and paste of scope display.
• Realistic on-screen virtual instrument.

One built-in virtual signal generator, providing:

• Frequency range 0.2Hz to 2MHz.
• Sine, square and triangle outputs.
• Output impedance 50Ω
• -20dB and –40dB attenuators.
• BNC and 2mm socket connections.
• DC offset control.
• Realistic on-screen virtual instrument.

One built-in virtual data logger, providing:

• Capture from oscilloscope and/or multimeters.
• Start/stop using timing or a trigger condition
• Grapher application to view and print results.

The VIP also includes the following features:

• Board type detection by barcode strip.
• Switched fault selection by password-protected virtual control panel.
• 0-12.7V variable DC supply setup by virtual control panel.
• Module supply on/off switching by virtual control panel.
• 4 x digital inputs.
• 2 x digital outputs.
• 100kHz I2C Interface.
• 2 x Programmable DC voltage sources, -9V to +9V at 100mA max.
• Built-in power supply unit.
• All D3000 power supplies and additional signals available on expansion connector.
