50 Ohm Load
The Keysight 909 series loads come in several models and options providing a
variety of frequency ranges and VSWRs. Also, they are available in either 50
ohm or 75 Ohm. Some examples include the:
909A: DC to 18 GHz
909C: DC to 2 GHz
909D: DC to 26.5 GHz
50 Ohm/75 Ohm Minimum Loss Pad
The Keysight 11852B is a low VSWR minimum loss pad that allows you to
make measurements on 75 Ohm devices using an analyzer with a 50 Ohm
input. It is effective over a frequency range of dc to 2 GHz.
75 Ohm Matching Transformer
The Keysight 11694A allows you to make measurements in 75 Ohm systems
using an analyzer with a 50 Ohm input. It is effective over a frequency range of
3 to 500 MHz.
AC Probe
The Keysight 85024A high frequency probe performs in-circuit measurements
without adversely loading the circuit under test. The probe has an input
capacitance of 0.7 pF shunted by 1 MΩ of resistance and operates over a
frequency range of 300 kHz to 3 GHz. High probe sensitivity and low distortion
levels allow measurements to be made while taking advantage of the full
dynamic range of the spectrum analyzer.
AC Probe (Low Frequency)
The Keysight 41800A low frequency probe has a low input capacitance and a
frequency range of 5 Hz to 500 MHz.
