KEYSIGHT N9961A is a handheld, lightweight, durable, microwave spectrum analyzer, interference analyzer, distance-tracking generator, preamplifier, and power meter. It provides two built-in ports with a maximum frequency of 44 GHz (Q band) and output power up to 4 dBm.
Engineers optimized the Keysight N9961A spectrum analyzer to excel in a dynamic spectral environment. You may encounter measurement challenges. For example, you might need to detect a weak signal in strong conditions.
This requires a high dynamic range. You may also need to identify small interference signals that are close together. This requires excellent phase noise performance.
The high dynamic range (TOI > +15 dBm) is impressive. The low phase noise (-111 dBc/Hz at 10 kHz offset) is also beneficial. Additionally, the fast sweep time helps make these tasks easier. The Keysight N9961A spectrum analyzer also provides a full power measurement suite and complete trace and state control.
KEYSIGHT N9961A Features:
- – Make accurate spectrum analyzer measurements (± 0.5 dB) without warmup.
- – Capture intermittent signals with 10 MHz gap-free, real-time bandwidth.
- – Characterize radar pulse profiles with a portable solution.
- – Perform over-the-air measurements for 5G TF and LTE.
- – Capture I/Q data for RF signal monitoring and analysis.
- – Use GPS/GNSS for geolocation and timestamping.
- – Carry one lightweight unit at 3.2 kg (7.1 lb).

With the Keysight N9961A FieldFox’s InstAlign capability, internal amplitude alignments occur automatically as environmental conditions change, without any user intervention. This provides unprecedented amplitude accuracy of ± 0.5 dB for analyzing the spectrum and measuring power.
The Keysight N9961A provides a spectrum analyzer IF output with 25 MHz bandwidth. This allows the use of a frequency downconverter. It can also digitize the signal with external test equipment.
You can use tools like a real-time scope or VSA for detailed signal analysis. FieldFox can connect to the 89600 VSA software (Keysight model number 89601B) via Ethernet to a Windows-based PC or tablet.
