FRA 51615
Unless stated specifically otherwise, the assumed conditions are sinusoidal waveform, a temperature of
23°C ±5°C, no more than 12 hours has passed since calibration has been performed after a warm-up period
of at least 30 minutes, and change in ambient temperature of not greater than ±5°C after calibration.
Unless stated specifically otherwise, the shell (outer cover) and signal grounds are connected to the
instrument enclosure (not isolated).
9.1 Oscillator section
The oscillator section can output an AC signal and the DC bias for measurement. The AC signal is output
from the
OSC
connector on the front panel. The DC bias can be output from either the
OSC
connector on
the front panel or the
DC BIAS OUT
connector on the rear panel. You can select the connector from which
the DC bias is output. If the
OSC
connector on the front panel is selected for DC bias output, the signal
output from the
OSC
connector is a composite of the AC signal and the DC bias.
9.1.1 Front panel OSC

Connector Insulated BNC connector (front panel,
OSC
)

Output waveform Sinusoidal, square, or triangular

Frequency
Setting range 10 µHz to 15 MHz
The quality of square and triangular waveforms deteriorates at frequencies
above 100 kHz.
Setting resolution 10 µHz
Accuracy ±10 ppm
Conditions: The instrument is operating on the internal reference clock.

Ω load
Distortion (sinusoidal) 0.2% or less, supplementary value
Conditions: 100 kHz or less, BW 500 kHz, 10 Vpk output

DC bias
The DC bias output is superimposed on the AC signal only when the DC bias output is set to the
OSC
connector on the front panel of the instrument.
Setting range -10 V to 10 V
Setting resolution 10 mV
Accuracy ±(|1% of DC bias setting | + 2% of AC amplitude se 30 mV)
Conditions: sinusoidal waveform, no load
