Agilent/ HP 3311A Function Generator, 1 MHz

The 3311A Function Generator offers wide functional capability at a modest price. This compact unit has seven decades of range from 0.1 Hz to 1 MHz. Pushbutton range and function selection add convenience to versatility. Added features normally not found on function generators in this price range are 10:1 voltage control and a separate pulse output suitable for synchronization or driving TTL logic circuits.

•  Output

Ten V p-p into 600 ohms (20 V p-p O.C.). This output may be attenuated by >30 dB by a variable attenuator and offset by ± 5 V. The DC offset allows the sine, square, and triangle functions to be positioned to the most desired level. This feature adds to the usefulness of all three functions.

• VCO

The DC coupled voltage control allows the use of an external source to sweep the 3311A > 10:1 in frequency.

•  Pulse Output

A separate TTL compatible pulse output provides current sinking for up to 20 TTL loads. The pulse has a 15/85 aspect ratio with a <25 ns rise time.
