What Active Probe can I use on my spectrum analyzer?

The P6243 is a 1 GHz probe. This probe must be powered; it requires an 1103 Power Supply. Also required is a BNC male to BNC male Coax Cable to connect from the 1103 power supply to the spectrum analyzer input. Because the probe is DC coupled, a DC Block must be used between the 1103 power supply, and the spectrum analyzer input.
