Sine Output

The SR850 can detect signals at harmonics of the reference frequency. The SR850 multiplies the input signal with digital sine waves at a multiple of the reference. Only signals at this harmonic will be detected. Signals at the original reference frequency are not detected and are attenuated as if they were noise.

Pressing this key selects the harmonic number field as the active entry field. The harmonic number may be adjusted using the knob or entered directly with the keypad. Harmonics up to 32767 times the reference can be detected as long as the harmonic frequency does not exceed 102 kHz.

If the harmonic number is set to N then the reference frequency is limited to 102 kHz/N.

The harmonic number is always displayed in the status bar at the bottom of the screen.

Pressing this key selects the Sine Output Amplitude as the active entry field. The sine amplitude may be set from 4 mVrms to 5 Vrms. The output impedance of the Sine Out is 50Ω. If the signal is terminated in 50Ω, the amplitude will be half of the programmed value.

When the reference mode is internal, this is the excitation source provid- ed by the SR850. When an external reference is used, this sine output provides a sine wave phase locked to the external reference. The SR850 provides a synchronous sinusoidal excitation signal even when an exter- nal TTL reference is used.

The rear panel TTL Output provides a TTL square wave at the reference frequency. This square wave is generated by discriminating the zero crossings of the sine output. This signal can provide a trigger or sync signal to the experiment when the internal reference source is used. This signal is also available when the reference is externally provided. In this case, the TTL Output is phase locked to the external reference.
