1. Above 50 GHz, FM is useable; however performance is not warranted.

2. Through any combination of path1, path2, or path1 + path2.

3. Speciﬁcations apply in CW and list/step sweep modes. During ramp sweep operation (Option 007), 3 dB bandwidth is typically 50 kHz to 10 MHz (FM1 path), and

50 kHz to 1 MHz (FM2 path).

4. At the calibrated deviation and carrier frequency, within 5 °C of ambient temperature at time of user calibration.
