Page 5: Introduction
The SG560 uses a robust output stage for the final driver. It is derived from DSL modems and is essentially a high power opamp. The opamp is capable of delivering 2.5W to a load before going into protective shutdown. -

Page 8: Generating A Frequency
Example: Enter a 0.5V peak to peak signal. Muting the Generator: Pressing SHIFT, MUTE will mute the output of the SG560. This sets the level to 0.0V and the offset to 0.0V. Pressing SHIFT, MUTE again will restore the level and offset to the previous... -
Page 9: Setting Generator Offset
For example, TTL (Transistor Transistor Logic) circuits require a 0V to 5V square wave. With a 0V offset the SG560 will generate a –2.5V to +2.5V square wave (average is 0 volts). To get the square wave to 0 to 5V we must add 2.5V to the AC waveform. In this case, enter an off- set of 2.5V. -

This can be set to whatever state is preferred for power up. Setting memory location to 0Hz, 0 level, and 0 offset simulates a mute condition, or the SG560 can be set up for the user’s Do not reproduce or distribute. - Page 11 Property of Ramsey Electronics, Inc.

Page 13: Using The Sg560 Differential Outputs
Using the SG560 Differential Outputs Since the SG560 has a differential output, the (+) jack is 180 degrees out of phase with the (-) jack. If the offset is at 5V the (-) jack has -2.5V of offset and the (+) jack has +2.5V in ref- erence to the internal common point. -
Page 14: Setting Meter Output Impedance
By running in 0 ohm configuration, you are able to have confidence in that the front panel setting of the SG560 is the same right at the jacks no matter what the load is. Normally with a known output impedance from a signal generator that impedance must be taken into account as a series resistor in a circuit under test. -
Page 15: Signal Descriptions
6 dB higher here in the pass band (since there is no voltage divider), it also has an additional “bump” that is unexpected from the filter design. This is due to the complex im- pedance of the filter reacting with the ideal source of the SG560. This is not a desirable re- sponse. -
Page 16: Dealing With Small Signal Levels And Noise
Dealing with Small Signal Levels and Noise: If small signal levels are needed for a test setup and the output noise of the SG560 is too high, an attenuator on the output of the SG560 will scale the signal level and the noise down to an acceptable level. - Page 17 DETAILED INFORMATION Your Notes: Property of Ramsey Electronics, Inc.
