Unit Can Calibrate Ultra High-Bandwidth Scopes

Building on the success of its popular 5800A calibrator, which can verify the performance of digital and analog oscilloscopes with bandwidths up to 600 MHz, the manufacturer has launched a new calibrator that can handle bandwidths as high as 2.1 GHz. The 2.1-GHz capability is offered as an option for the new 5820A calibrator, as well as for the existing 5800A unit, with the former also offering as an option a five-channel output for facilitating hands-free automated calibration of multi-channel scopes. Other improvements and features built into the 5820A include: 600-MHz leveled sine/300-ps edge performance, with 2.1-GHz leveled sine/150-ps edge offered as an option; front panel current loop for calibrating current probes; dc voltage measurement to calibrate reference signals; and ±0.33 ppm frequency accuracy to cover counter functions and to provide better test margins.
