The Model 455 DSP gaussmeter uses digital signal processing for a dc to 20-kHz frequency response with peak field detection to 50-μsec pulse widths.
The temperature-compensated unit lists a rated dc accuracy of 0.075% with 53/4-digit resolution. A message-based display reads out probe temperature as well as RMS mode frequency. Most commonly used functions are accessible via one or two keystrokes from the front panel.
