Line Settings
The signal generator has an autoranging line voltage input. The available ac power source must meet
the following conditions:
Voltage: 100/115 volts nominal (100- 120 volts)
230/240 volts nominal (220- 240 volts)
Frequency: for 100/115 volts: 50/60 (400 Hz nominal E8257D and E8663D only)
for 230/240 volts: 50/60 Hz nominal
Power: E8257D and E8663D PSG analog models: 350 watts maximum
E8267D PSG vector models: 450 watts maximum
CAUTION Damage to the signal generator may result if the supply voltage is not within the
specified range.
Connecting the AC Power Cord
This is a Safety Class 1 Product provided with a protective earth ground incorporated into the power
cord. The front panel switch is only a standby switch; it is not a line switch. The AC power cord is
the disconnecting device that disconnects the signal generator mains circuits from the mains supply.
Alternatively, an external switch or circuit breaker, readily identifiable and easily reached by the
operator, may also be used as a disconnecting device.
Disconnecting power to an instrument with a high stability timebase may require a longer warm- up
period before it meets specifications. Perform the following steps when connecting the ac power cord:
WARNING Personal injury may occur if there is any interruption of the protective conductor
inside or outside of the signal generator. Intentional interruption is prohibited.
CAUTION Damage to the signal generator may result without adequate earth grounding. Always
use the three- prong AC power cord supplied with the signal generator.
1. Ensure that the power cord is not damaged.
2. Install the signal generator so that one of the following items is readily identifiable and easily
reached by the operator: AC power cord, alternative switch, or circuit breaker.
3. Insert the mains plug into a socket outlet provided with a protective earth grounding.
