P6701
The Tektronix P6701 is a 700 MHz optical/electrical converter for 450 to 1050 nm input wavelengths.
It attaches to a scope or 1103 power supply through a Tekprobe BNC connector.
Sister model P6702 offers 500 MHz bandwidth for 1000 to 1700 nm input wavelengths. The P6751 Spatial Input Head can be used to sample non-fibre input signals, e.g. on an optical bench.
