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:

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.

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 M Ω 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.

Broadband Preamplifiers and Power Amplifiers

Preamplifiers and power amplifiers can be used with your spectrum analyzer to
enhance measurements of very low-level signals.
— The Keysight 83006A preamplifier provides a minimum of 26 dB gain from
— The 11909A low noise preamplifier provides a minimum of 32 dB gain from

RF and Transient Limiters

The Keysight 11867A and N9355C RF Limiters protect the analyzer input
circuits from damage due to high power levels. The 11867A operates over a
frequency range of dc to 1800 MHz and begins reflecting signal levels over
1 mW up to 10 W average power and 100 watts peak power. The N9355C
microwave limiter (0.01 to 26.5 GHz) guards against input signals over
10 milliwatts up to 1 watt average power.
