to 50or 75Ω, or to 0for driving into high impedance. The output

 

voltage can be attenuated by either 0 or 20 dB when 50

or 75output

 

impedance is selected. Output attenuation is unavailable with the 0mode

 

(high impedance).

 

 

The main output terminal may be enabled or disabled under user control.

 

When disabled, the output appears as an open circuit.

This output is also

 

overload protected via an output relay. The output relay automatically opens

 

when an overload condition is detected and disconnects the output from the

 

load. An overload occurs if the sum of the inputs, plus the output of the

 

offset DAC, is excessive, or if the output current limit is reached. The relay

 

remains open until the overload condition is corrected and the output is reset

 

by the user. Refer to Appendix A of this manual for these specifications.

a maximum output level of ±1 Vpeak into a 50/75load. One of the

 

outputs is a non-inverting amplifier (same polarity as the input); whereas the

 

other is an inverting amplifier (opposite polarity as the input). Into a high

 

impedance, each input has a maximum gain of two. The output impedance

 

of each amplifier can be independently set to either 50

or 75.

With two low level output terminals, output signals can be taken from either of the terminals with respect to ground, or across the two terminals (in series). Output signals taken across the two terminals will result in two times the input voltage. Figure 1-5 shows the circuitry of the output signal taken across the two terminals.
