Keysight N9010A EXA Service Guide 19OverviewSignal Analyzer Accessories50 Ohm LoadThe Keysight 909 series loads come in several models and options providing avariety of frequency ranges and VSWRs. Also, they are available in either 50ohm or 75 Ohm. Some examples include the:909A: DC to 18 GHz909C: DC to 2 GHz909D: DC to 26.5 GHz50 Ohm/75 Ohm Minimum Loss PadThe Keysight 11852B is a low VSWR minimum loss pad that allows you tomake measurements on 75 Ohm devices using an analyzer with a 50 Ohminput. It is effective over a frequency range of DC to 2 GHz.75 Ohm Matching TransformerThe Keysight 11694A allows you to make measurements in 75 Ohm systemsusing an analyzer with a 50 Ohm input. It is effective over a frequency range of3 to 500 MHz.AC ProbeThe Keysight 85024A high frequency probe performs in-circuit measurementswithout adversely loading the circuit under test. The probe has an inputcapacitance of 0.7 pF shunted by 1 MΩ of resistance and operates over afrequency range of 300 kHz to 3 GHz. High probe sensitivity and low distortionlevels allow measurements to be made while taking advantage of the fulldynamic range of the spectrum analyzer.AC Probe (Low Frequency)The Keysight 41800A low frequency probe has a low input capacitance and afrequency range of 5 Hz to 500 MHz.Broadband Preamplifiers and Power AmplifiersPreamplifiers and power amplifiers can be used with your spectrum analyzer toenhance measurements of very low-level signals.— The Keysight 8447D preamplifier provides a minimum of 25 dB gain from100 kHz to 1.3 GHz.— The Keysight 87405A preamplifier provides a minimum of 22 dB gain from10 MHz to 3 GHz. (Power is supplied by the probe power output of theanalyzer.)— The Keysight 83006A preamplifier provides a minimum of 26 dB gain from10 MHz to 26.5 GHz.
