1. POWER Switch . This is the main power switch. When turning the instrument on,

there may be a delay of several seconds before the instrument appears to respond.

2. OVERLOAD Indicator . When the instrument is powered, this indicator is normally

green, indicating normal operation. If this indicator is yellow, an internal automatic

overload protection circuit has been tripped. If the unit is overloaded (by operating at

an exceedingly high duty cycle or by operating into a very low impedance), the

protective circuit will disable the output of the instrument and turn the indicator light

yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after

which the instrument will attempt to re-enable the output (i.e. light green) for about 1

second. If the overload condition persists, the output will be disabled again (i.e. light

yellow) for another 5 seconds. If the overload condition has been removed, the

instrument will resume normal operation.

This overload indicator may flash yellow briefly at start-up. This is not a cause for

concern.

3. IN CONNECTOR. The input is applied to this SMA connector. The input voltage

must always lie between -300 mV and +300 mV. Voltages outside of this range may

damage the instrument. The input impedance is 50Ω.

4. OUT Connector . This is the output. It can drive loads impedances of 50 Ohms or

higher.
