Output Terminals

  • CCS: 1.1\ mA Constant Current Source. On/Off using Check-Button Enable CCS.
  • PV1: Programmable Voltage, \pm 5\ V range. Can be set using the Slider or Text-Entry widget
  • PV2: Similar to PV1, but ranges from - 3.3\ V to + 3.3\ V
  • SQ1: Square Wave Generator, swings from 0 to 5\ V. Frequency can be set from 1\ Hz to 5\ kHz.
  • SQ2: Same as SQ1, but available as an option of WG.
  • OD1: Digital Output, voltage can be set to 0 or 5\ V.
  • WG: Waveform Generator. Frequency from 1\ Hz to 5\ kHz. Amplitude can be set to 3\ V, 1\ V or 80\ mV. Can be set to Sine, Triangular or Square. In Square mode the output is on SQ2, with 0 to 5\ V swing.
  • -WG: Inverted output of WG

Input Terminals

  • IN1: Input for measuring Capacitance. Push-Button provided for measurement.
  • IN2: Input for measuring frequency of digital signals, swinging between 0 and 3 to 5\ V. Push-Button provided for measurement.
  • SEN: Input for measuring resistance. This point is internally connected to 3.3\ V via a 5.1\ k\Omega resistor
  • A1: Voltage measurement point, functions as voltmeter and oscilloscope. Maximum Input range \pm\ 16\ V, range is selectable from pull down menu. AC/DC mode selection by slider switch on the box.
  • A2: Same as A1, but no AC coupled mode
  • A3: Voltage measurement in \pm\ 3.3\ V. Small signals can be amplified by connecting a resistance from Rg to Ground
  • MIC: Condenser microphone input, output appears as the fourth channel of the oscilloscope
  • Rg: Gain resistor for A3. Gain = 1 + \frac{R_{g}}{100}. For example connecting a 1\ k\Omega resistor gives a gain of 11.
