Template:Plugin Sidebar 2 The Tektronix 7D12 is an A/D converter (digital meter) plug-in for 7000-series scopes.

The 7D12 accepts plug-in modules M1, M2, or M3.

  • M1 is a digital multimeter module with DC voltage, resistance and temperature (with P6058 or P6430) ranges.
  • M2 is a sample and hold module that can measure voltage from ground to a selected point, or the difference voltage between two points defined by a trigger signal. When triggered by the delayed gate signal from a time base, this allows cursor-like measurements to be made. The module has an aperture time of only 10 ns. With repetitive signals, the period between the sampled points can be as short as 30 ns, in single shot mode it must be at least 150 μs.
    Input sensitivity is selectable between ±2 V (100/200/500 mV/Div) and ±20 V (1/2/5 V/Div) ranges. The input has a ring to detect a ×10 probe with readout pin (P6055 recommended) and adjusts the display accordingly. Signal bandwidth is 25 MHz.
  • M3 is a True RMS module.
  • 067-0700-00 is a calibration fixture.
