Esd Caution - Anritsu Spectrum Master MS2712E User Manual

1-4 Instrument Care and Preventive Maintenance
Connecting Procedure
1. Carefully align the connectors. The male connector center pin must slip concentrically
into the contact fingers of the female connector.
2. Push connectors straight together. Do not twist or screw them together. A slight
resistance can usually be felt as the center conductors mate.
3. To tighten, turn the connector nut, not the connector body. Major damage can occur to
the center conductor and to the outer conductor if the connector body is twisted.
4. If you use a torque wrench, initially tighten by hand so that approximately 1/8 turn or
45 degrees of rotation remains for the final tightening with the torque wrench.
Relieve any side pressure on the connection (such as from long or heavy cables) in order
to assure consistent torque. Use an open-end wrench to keep the connector body from
turning while tightening with the torque wrench.
Do not over-torque the connector.
Disconnecting Procedure
1. If a wrench is needed, use an open-end wrench to keep the connector body from turning
while loosening with a second wrench.
2. Complete the disconnection by hand, turning only the connector nut.
3. Pull the connectors straight apart without twisting or bending.

ESD Caution

The Spectrum Master, like other high performance instruments, is susceptible to electrostatic
discharge (ESD) damage. Coaxial cables and antennas often build up a static charge, which
(if allowed to discharge by connecting directly to the instrument without discharging the
static charge) may damage the Spectrum Master input circuitry. Instrument operators must
be aware of the potential for ESD damage and take all necessary precautions.
Operators should exercise practices outlined within industry standards such as JEDEC-625
(EIA-625), MIL-HDBK-263, and MIL-STD-1686, which pertain to ESD and ESDS devices,
equipment, and practices. Because these apply to the Spectrum Master, it is recommended
that any static charges that may be present be dissipated before connecting coaxial cables or
antennas to the Spectrum Master. This may be as simple as temporarily attaching a short or
load device to the cable or antenna prior to attaching to the Spectrum Master. It is important
to remember that the operator may also carry a static charge that can cause damage.
Following the practices outlined in the above standards will ensure a safe environment for
both personnel and equipment.
