The HP 8591A High performance portable Spectrum Analyzer offers frequency accuracy and a wide range of options for applications that demand higher performance. The HP 8591A has a frequency range of 9 kHz to 1.8 GHz and amplitude range of -115 to + 30 dBm. An internal preselector, and an amplitude range of -114 to + 30 dBm. It has standard 7.5 ppm frequency accuracy that can be improved with an optional precision frequency reference to marker count accuracy of ± 230 Hz at 1 GHz or ± 2.3 kHz at 18 GHz. The HP 8591A comes with a built-in memory card reader that enables you to load HP's custom measurement personalities and measurement data into the spectrum analyzer using 32-Kbyte memory cards. A catalog function allows you to determine the exact content of information stored on your memory cards or within internal memory. Specifications. Frequency range: 9 kHz to 1.8 GHz, 1 MHz to 1.8 GHz (opt 001). Span range: 0 Hz (zero span), 10 kHz to 1.8 GHz. Span accuracy: Span = 10 MHz: ±2% of span, Span > 10 MHz: ±3%. Sweeptime Range: Span = 0 Hz or > 10 kHz: 20 ms to 100 s. Sweeptime Accuracy: 20 ms to 100 s: ±3%. Amplitude range: -115 to +30 dBm. Displayed average noise level: <= -115 to <= -113 dBm.
