The HP 85082A Input Module (300 kHz to 2 GHz, 50 ohm Type N inputs) is for use with a 8508A and HP 70138A vector voltmeter. It provides the accuracy and dynamic range to make measurements on active and passive components. Module Specifications with a 8508A or 70138A. Frequency Range: 300 kHz to 2 GHz. Maximum Input: + 16 dBm, ± 50 Vdc. A (ref) Channel Minimum: - 47 dBm, 100 kHz to 300 kHz; -47 dBm, 300 kHz to 3 MHz; - 57 dBm, 3 MHz to 2 GHz. B Channel Noise Level: - 87 dBm. Input Crosstalk: > 100 dB, 1 MHz to 500 MHz > 80 dB, 500 MHz to 1 GHz, > 70 dB, 1 GHz to 2 GHz. Magnitude Accuracy Absolute accuracy (A, B 100 mV, 15° to 30° C): + 1/ -1.5 dB, 100 kHz to 300 kHz, to + 1/ - 2 dB, 1.5 GHz to 2 GHz. Magnitude Accuracy Ratio accuracy (A, B 100 mV, 15° to 30° C): ± 1 dB, 100 kHz to 300 kHz, to ± 1 dB, 1.5 GHz to 2 GHz. Magnitude Accuracy Phase accuracy (A, B 100 mV, 15° to 30° C): ± 4, 300 kHz to 1 MHz, to (± 12, 1.5 GHz to 2 GHz. Search and Lock Time: Lockup (within one range): 40 ms, frequencies up to 3 MHz; 20 ms, frequencies greater than 3 MHz.
