  • Quick and Easy Oscilloscope Calibration to 600MHz
    The 5045 is a versatile, high accuracy calibrator capable of calibrating digital and analogue oscilloscopes, timer/counters, and frequency meters.
    It provides a wide range of outputs for amplitude, frequency, period and bandwidth. Amplitude calibration is achieved by a DC signal or 1kHz square-wave, ranging from 1mV to 220V (2V max for 50 ohm loads). Deviation up to ±9.99% allows fine adjustment of amplitude and direct readout of error. 

    Accurate frequencies are generated from a temperature controlled quartz crystal oscillator. Alternatively a 10MHz reference input in can be used. Timing accuracy of 0.1ppm is suitable for most oscilloscopes and timer counters. A precise square-wave output provides a fast rise time of less than 300ps, which allows bandwidth testing up to 600MHz.

    Simple Operation
    Functions and ranges are easily accessed from the front panel. Increase and decrease keys per digit, are used to quickly set the output value. Deviation control then enables the user to finely adjust the output value as a percentage (+/-9.99%). All this information is shown on an easy to read LED display.

    Virtual Front Panel Software
    The 5045 is supplied as standard with Time Electronics’ windows based ‘Virtual Front Panel’ interface. This enables the user to control the instrument via a laptop or PC. 

    2.2GHz Levelled Sine-Wave Option
    For precise bandwidth determination and frequency response analysis the 2.2GHz option is available. The ability to sweep the frequency output from 50MHz to 2.2GHz and adjust the amplitude from 0.5V to 1.5V pk-pk ensures accurate analysis of oscilloscope input amplifiers.

    Current Probe Calibration
    For calibration of oscilloscope current probes an external adaptor is available. This converts the 5045’s amplitude output to current and covers the range 0.1mA to 100mA pk-pk, 0.2% accuracy, DC or 1kHz.

    Rubidium frequency reference
    Enhanced timing performance is available by specifying the rubidium high stability frequency reference option (9762). This option achieves timing accuracies required to calibrate high performance timer/counters to 1 part in 10^10.

    EasyCal Software - Manage, Automate and Optimise the Calibration Process
    To automate the oscilloscope calibration process the 5045 can be controlled using Time Electronics’ EasyCal calibration software. This provides increased speed of calibration and consistency of results. Easily produce calibration certificates and reports to ISO 9001, ISO 17025, and other international quality standards.
