The 5045 is capable of calibrating a wide range of oscilloscopes and timer/counters, providing a 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 50ohm loads).

Deviation up to +/-9.99 per cent allows fine adjustment of amplitude and direct readout of error.

Accurate frequencies are generated from a temperature controlled quartz crystal oscillator.

A precise square-wave output provides a rise time of less than 300ps, which allows bandwidth testing up to 600MHz.

Functions and ranges can be accessed from the front panel.

Increase and decrease keys are used to set the output value.

Deviation control then enables the user to finely adjust the output value as a percentage (+/-9.999 per cent).

All this information is shown on a clear LED display.

Supplied as standard is the windows-based Virtual Front Panel interface from Time Electronics, which allows the user to control the 5045 via a laptop or PC.

For precise bandwidth determination and frequency response analysis the 2GHz option is available.

The ability to sweep the frequency output from 100MHz to 2GHz and adjust the amplitude to 0.5V, 1.0V and 1.5V pkpk ensures accurate analysis of oscilloscope input amplifiers.

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 per cent accuracy, DC or 1kHz.

Enhanced timing performance is also available by specifying the rubidium frequency reference option (9762).

This option achieves timing accuracies required to calibrate high-performance timer/counters to one part in 10.

To automate the oscilloscope calibration process, the 5045 can be controlled using Easycal calibration software.
