Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
►
NOTICE! Electrostatic discharge can damage the electronic components of the
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
During operation, if the firmware observes a serious unexpected disturbance (e.g. due
to ESD), it resets some hardware components and initiates a new alignment to ensure
proper instrument functioning. Then it restores the user settings to the state before the
disturbance.
3.1.6 Connecting to power
For safety information, see "Connecting to power and grounding" on page 17.
The R&S MXO 4 can be used with different AC power voltages and adapts itself auto-
matically to it.
The nominal ranges are indicated on a label near the power connector on the instru-
ment and in the data sheet.
1. Plug the AC power cable into the AC power connector on the rear panel of the
product. Only use the AC power cable that is delivered with the product.
2. Plug the AC power cable into a power outlet with ground contact.
The required ratings are listed next to the AC power connector and in the data
sheet.
3.1.7 Switching on or off
The instrument is switched on or off with the power switch and the [Power] key. The
[Power] key is located in the bottom left corner of the front panel. The power switch is
located at the rear panel of the instrument.
