General Safety Considerations
General Safety Considerations
The HP 71500A, HP 70820A, and Agilent N1015A products have been
designed and tested in accordance with the standards listed on the Manufac-
turers Declaration of Conformity, and has been supplied in a safe condition.
This documentation contains information and warnings that must be followed
by the user to ensure safe operation and to maintain the product in a safe con-
dition.
Install the instrument according to the enclosure protection provided.
Instruments do not protect against the ingress of water.
This instrument protects against finger access to hazardous parts within the
enclosure.
Install the instrument so that the ON/OFF switch is readily identifiable and is
easily reached by the operator. The ON/OFF switch or the detachable power
cord is the instrument disconnecting device. It disconnects the mains circuits
from the mains supply before other parts of the instrument. Alternatively, an
externally installed switch or circuit breaker (which is readily identifiable and
is easily reached by the operator) may be used as a disconnecting device.
The front panel LINE switch disconnects the mains circuits from the mains
supply after the EMC filters and before other parts of the instrument.
Position the instruments so it is not difficult to operate the disconnecting
device.
W A R N I N G
If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal
condition (in which all means for protection are intact) only. Altitude
up to 2000 Meters, temperature 0 to 40 °C.
W A R N I N G
No operator serviceable parts inside. Refer servicing to qualified
service personnel. To prevent electrical shock do not remove covers.
W A R N I N G
This is a Safety Class 1 Product (provided with a protective earthing
ground incorporated in the power cord). The mains plug shall only be
inserted in a socket outlet provided with a protective earth contact.
Any interruption of the protective conductor inside or outside of the
instrument is likely to make the instrument dangerous. Intentional
interruption is prohibited. iv
General Safety Considerations
W A R N I N G
To prevent electrical shock, disconnect the instrument from mains
before cleaning. Use a dry cloth or one slightly dampened with water
to clean the external case parts. Do not attempt to clean internally.
W A R N I N G
For continued protection against fire hazard, replace N1015A line fuse
only with same type and ratings (1A/250V, part number 2110-1320).
The use of other fuses or materials is prohibited. v
General Safety Considerations
C A U T I O N
Connectors are easily damaged when connected to dirty or damaged cables and
accessories. When you use improper cleaning and handling techniques, you
risk expensive instrument repairs, damaged cables, and compromised
measurements. Before you connect any cable to the Agilent 71501D, clean it
properly.
C A U T I O N
Total input signal power to the HP 70820A modules front-panel RFINPUT
connectors must not exceed +16 dBm. Because there is no RF input attenuator,
power in excess of +16 dBm may damage the instrument. The largest
measurable power level before signal compression is +4 dBm.
C A U T I O N
To avoid damage, do not exceed +10 dBm input power or
±
2 V DC to any
N1015A front panel RF inputs. Do not apply DC voltage exceeding
±
10V to the
N1015A Jitter Modulation Input.
C A U T I O N
The N1015A circuitry can be damaged by electrostatic discharge (ESD). Avoid
applying static discharge to the N1015A RF connectors and jitter modulation
connectors.
C A U T I O N
This product is designed for use in Installation Category II and Pollution
Degree 2 per IEC 61010-1C and 664 respectively.
C A U T I O N
Always use the three-prong ac power cord supplied with the instruments.
Failure to ensure adequate earth grounding by not using this cord may cause
instrument damage.
C A U T I O N
The N1015A instrument has autoranging line voltage input. Be sure the supply
voltage is within the specified range (110/115/230/240, 50/60 Hz, 110 Watts).
C A U T I O N
Use of controls or adjustment or performance of procedures other than those
specified herein may result in hazardous radiation exposure. vi

Analysis with the Agilent 71501D
The Agilent 71501D jitter analysis system provides advanced analysis of high-
speed digital communication waveforms and the components which generate
them. The jitter analyzer configuration performs automatic compliance and
network equipment testing, to SONET, SDH, and custom standards. In addi-
tion, it can perform diagnostic measurements of the jitter spectrum and wave-
form.
