    The CG 5011 is used either manually, or as a part of an automatic calibration system to to calibrate a wide range of oscilloscope parameters. The unit occupies three slots in this TM5006 mainframe, and is programmable by GPIB. The unit comes complete with a Tektronix 015-0311-01 Programmable Pulse Head, which is essential for operation and a Tektronix 015-0310-01 Comparator Head.

    DESCRIPTION:

    The Tektronix CG 5011 Programmable Calibration Generator is a source of calibrated timing signals, calibrated amplitude voltage and current waveforms, and pulses with low distortion edges. The CG 5011 is used to calibrate and check oscilloscope performance characteristics.

    The CG 5011 operates in five basic modes:

  • VOLTAGE - as a voltage source it is used to check the gain accuracy of vertical and horizontal amplifiers.
  • CURRENT - as a current source it is used to check the accuracy of current probes and amplifiers.
  • EDGE - as a source of low distortion edges it is used to check the transient response of amplifiers and attenuator networks.
  • FAST EDGE - with the Pulse Head accessory, it is used to check the transient response (rise time) of vertical amplifiers (beyond the EDGE mode capability).
  • MARKERS - as a time mark source it is used to check the timing accuracy of horizontal sweep rates up to10 ns/division. The CG 5011 has marks to 0.5 ns.
