Fluke 207-13 receiver comparator
Fluke 207-13 Receiver Comparator
Powers up. Retired lab standard, operational at time of retirement.
The 207-13 VLF Receiver/Comparator with additional frequency comparator input (option 5) provides frequency coverage of 8.0kHz to 31.9kHz in steps of 100Hz with an additional 60kHz channel. Short and long term stability is +/- 0.5 us. Under laboratory conditions intrinsic calibration accuracy (relative to received VLF carrier) is +/- 1x10 E-11 per 24 hours. Receiver sensitivity is 10 nV signal at 50-ohms antenna input terminal. A built-in recorder on the front-panel records a time history of the accumulated phase difference between the local standard and VLF carrier, up to 9999.9 us.
