[ Summary ][ Features ][ Specifications ][ Ordering ][ Assistance ]

Product Summary

The HP 8568B Opt 462 is an excellent EMI receiver with 6 dB bandwidths. In addition to enhanced instrument capability for MIL-STD 461A/ 3/C and the new 461D EMI measurements, HP 8568B Opt 462 makes all commercial EMI and general-purpose measurements. This EMI receiver is compatible with the HP 85650A quasi-peak adapter, HP 85685A RF preselector, HP 85869A EMI measurement software, and HP 85867A EMI receiver functions program. The HP 8568B Opt 462 also functions as a high-performance, 100 Hz to 1.5 GHz, spectrum analyzer which fits into many applications, including automated broadband signal surveillance and component stimulus-response testing. Existing HP 8568B spectrum analyzers can be modified to include Option 462.

The marker must be positioned at least 20 dB above the noise or the intersection of the signal with an adjacent signal and more than four divisions up from the bottom of the CRT. Counter resolution is normally a function of frequency span but may be specified directly using SHIFT =. Accuracy For spans <=100 kHz: ą(frequency reference accuracy x displayed frequency +2 x frequency counter resolution) For spans >100 kHz but <=1 MHz: ą(frequency ref accuracy x displayed frequency +10 Hz + 2 x frequency counter resolution) For spans > 1 MHz: ą(10 kHz + frequency counter resolution) Frequency Span 100 Hz to 1500 MHz over 10-division CRT horizontal axis. Variable from data knob, or numeric/unit keyboard in approximately 1% increments; step keys change span in a 1, 2, 5 sequence. In zero span, the instrument is fixed tuned at the center frequency. Full Span: (0-1500 MHz) is immediately executed with 0-1.5 GHz or INSTR PRESET keys Frequency Span Accuracy (100 Hz to 1500 MHz) For spans >1 MHz: ą2% of the indicated frequency separation between two points +0.5% span For spans <=1 MHz: ą5% of frequency separation +0.5% span Resolution Bandwidths Range Opt 462: 6 dB bandwidths for EMI measurements Standard: 3 dB bandwidths of 10 Hz to 3 MHz in a 1, 3, 10 sequence.
