Features:

• Broad bandwidth with flat frequency response, +/- 1.5 dB, ensures excellent measurement accuracy and helps you achieve the best product specifications
• Low noise floor, less than -130 dBm/Hz at 10 MHz to 12 GHz, which allows measurements to be made at a low signal amplitude
• Convenient biasing from Keysight’s RF and microwave instruments probe power port or bench top power supply for user flexibility

Note: Probe head not included, must be ordered separately.
