5045 Oscilloscope Calibrator

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 1 kHz square-wave, ranging from 1 mV to 220 V (2 V max for 50 ohm loads). Deviation up to ± 9.99 % allows fine adjustment of amplitude and direct read-out of error.

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

The 5045 is supplied with a Windows based virtual control interface software. This allows the user to control the instrument via a laptop or PC. EasyCal software is available as an option to enable automated testing and calibration management.

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 a clear, easy to read LED display.

2.2 GHz Levelled Sine-Wave Option

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

External options include a rubidium high stability frequency reference (model 9762). This enhances timing performance and achieves accuracies required to calibrate high performance timer/counters to 1 part in 1010.

EasyCal Calibration Software

The 5045 calibrator can be controlled via Time Electronics EasyCal software, to automate the calibration process. This provides increased speed of calibration and consistency of results.

Produce traceable calibration certificates and test reports for quality standards with additional uncertainty information for ISO 17025 conformance.
