[1] Extended frequency range to 350 MHz is provided, but flatness is not specified. Amplitude is limited
to 3 V for frequencies above 250 MHz.
[2] Within one hour after reference amplitude setting, provided temperature varies no more than
±
5°C.
[3] At frequencies below 120 kHz, the resolution is 10 Hz. For frequencies between 120 kHz and
999.9 kHz, the resolution is 100 Hz.

±
(25 ppm + 15 mHz) for frequencies of 1 MHz and below.
