Frequency range: 50 Hz to 1 MHz
Resolution: 1 Hz resolution
The output frequency can be controlled according to four operating modes: digital setting by six lever / indicator switches, remote programming in parallel BCD code or through the IEEE bus, analog setting by two verniers with graduated scale, frequency sweep by external signal.
Four output signals are simultaneously available:
Main output with push-button selectable impedance: 75 ohms coaxial, 150 ohms balanced, 600 ohms balanced or low-impedance balanced (key 0 ohm)
Auxiliary output with Z < 1 ohms impedance
Square-wave output with 5 V or 10 V amplitude
Tracking output delivering a signal with 4 MHz offset with respect to the dialed or programmed frequency

Long term stability of output signal is defined by high accuracy of GPS Caesium references and approaches 1×10-12.
Short term signal quality is defined by internal TCXO clock source providing high-quality, low phase noise clock signal with sub-picosecond RMS jitter.
Digital PLL allows main output reference frequency to have almost any value between 400Hz and 810MHz.
Output signal is a square wave at 3.3V CMOS levels with 50 Ohms characteristic impedance. Output drive level can be adjusted.
