Output at 50Ω
2.8 Vpp, 1 Vrms, 13 dBm

Square wave

Default impedance per 3-output group
50Ω × 2 + 75Ω × 1
Impedance mix can be configured

Choose the 50Ω / 75Ω mix before shipment. The waveform allocation remains 3 sine + 3 square. Contact customer service before ordering.

Fivecompartments separate power and clock circuits.

The transformer, linear supply, AC input, OCXO thermal chamber, and output board each occupy a dedicated compartment machined into one CNC aluminum chassis.

Flexible grounding for multi-component systems.

Choose the chassis-earth connection at the rear panel, with a separate terminal for an external ground lead.

FLOAT

Disconnects the chassis from AC protective earth.

GROUND

Connects the chassis to AC protective earth.

TERMINAL

Provides a connection point for an external ground conductor.
