A pre-owned Agilent E7402A brings in-house EMI pre-compliance within reach. This spectrum analyzer features synthesized tuning from 100 Hz to 3 GHz, 1 Hz digital RBW and built-in quasi-peak detectors that reveal emissions ordinary spectrum analyzers miss.

The 20 dB pre-amp pushes the noise floor to -166 dBm/Hz, making it sensitive enough to detect even the most subtle RF leaks. With SCPI/LAN/GPIB control, optional tracking generator, and a rugged 15 kg form factor, this analyzer is suitable for both bench and field applications at a fraction of the cost of new instruments.
