2.0 Installation and setup.

This section discusses how to properly connect the 4071 to your equipment. The following diagrams identify the connectors and show typical hookups.

Figure 2.0-1: Front Panel Connectors

1. SYNC out connector

This connector provides a TTL/CMOS signal, +5V logic level useful for driving digital circuitry. This output is capable of driving TTL or CMOS loads with current capability +/ - 24 mA.

In all sinewave and modulation modes except sweep, this connector supplies squarewave version of the signal on the SIG Out connector. It has a fixed 50% duty cycle.

In the Sweep mode, this connector provides a high going pulse at the beginning of each sweep.

In the Arbitrary Waveform Generator mode, the user may set this output high or low on any data point(s) in the Arbitrary Waveform. This feature could be used to create a pattern of logic pulses or a triggering or synchronizing signal, which accompanies an analog waveform.

In the Function Generator mode, a high going pulse is given on this output at the start of each function waveform. This useful feature allows the user to synchronize the functions to other events.

In the Pulse Generator mode, this output follows the SIG Out signal. The signal on this output has the same frequency and duty cycle as signal on the SIG out connector. However the signal on this connector is not variable in amplitude and offset; it set to +5V, to provide a convenient interface with TTL/CMOS digital logic.

2. SIG Out connector

This is the main signal output. It has a source impedance of 50? , and can supply signals as large as 20 Vp -p into an open circuit or 10Vp -p into a 50O load. It can also supply a DC offset voltage of +/ - 6.000V into a 50O load.

*** Caution ***

Although the output is protected against short circuits, you should NEVER connect SIG Out to a voltage

or signal source. This may overload the output and damage the 4071.
