Is the YBT250 accurate enough to set the frequency of my Base Station (BTS)?

Is the YBT250 accurate enough to set the frequency of my Base Station (BTS)?

The NetTek is accurate to 0.5 ppm without a GPS, or 0.015ppm with a GPS.
At 2 GHz, without a GPS, this translates to 2000 * 0.5 = 1000 Hz error.
With a GPS, it's 2000 * 0.015 = 30 Hz.
A BTS needs to be accurate to 0.05 ppm, or 100 Hz at 2 GHz.
The NetTek requires a YBGPS1 to accurately make this measurement at the carrier frequency.
