Safety requirement
This section contains information and warnings that must be observed to keep
the instrument operating under the corresponding safety conditions. In addition to
the safety precautions specified in this section, you also have to follow common
safe operating procedures.
Safety terms and symbols
When the following terms or symbols appear on the front panel, rear panel,
or this manual, it indicates particular attention should be paid.
Indicates potential injuries or hazards that may happen.
Indicates electric shock that may happen.
Indicates measurement grounding
Indicates safety grounding.
This is a start/standby switch. Press the switch, the VNA will switch between the working state
and the standby state. The switch could not power off the device, to completely power off the
VNA, the power cord must be removed from the AC socket.
Indicates “AC”.
CAUTION
Indicates potential damages to the instrument or other property that may happen.
WARNING
Indicates potential injuries or hazards that may happen.
Operating environment
Use in a clean and dry indoor environment with an ambient temperature range
from 0°C to 40°C.
Note: Direct sunlight, electric heaters, and other direct heat sources, should
be considered when evaluating the ambient temperature.
WARNING: Do not operate the VNA in an explosive, dusty or humid environment.
This instrument meets the EN 61010-1 standard, and has the following
restrictions:
Installation (overvoltage) category: Class II (electric supply connector) and
Class I (measure terminal)
Pollution level: Class II

3 SNA5000A Vector Network Analyzer User Manual
Protection level: Class I
Note:
Installation (overvoltage) category Class II indicates the local supply level is
suitable for equipment connected to the AC power supply.
Installation (overvoltage) category Class I indicates the signal levels suitable
for terminals connected to the RF source.
Pollution level Class II indicates it only occurs in a dry and non-conductive
environment, sometimes we should consider the temporary conductivity caused
by concentration.
Protection level Class I indicates grounding equipment, it prevents electric
shock by connecting the equipment to the ground wire.
CAUTION: Do not apply excessive pressure or strike the surface of the touch screen.
CAUTION: Do not exceed the maximum voltage marked on the front panel connectors.
Cooling requirement
This instrument is cooled through a built-in fan. To keep adequate ventilation,
a gap of at least 15 cm should be left on both sides, as well as the front and rear
panels of the instrument.
CAUTION: Do not block the vents located along the side and real panel of the instrument.
CAUTION: Do not let any external objects enter the instrument through the vents.
AC power supply
The instrument accepts 100-240V, 50/60/400Hz AC power. The maximum
power consumption is 90W with complete options.
Note: The instrument can operate within the following input ranges:
Voltage range:
90 - 264 Vrms
90 - 132 Vrms
Frequency range:
47 - 63 Hz
380 - 420 Hz
Power supply and grounding
The instrument has a three-terminal plug and an IEC320 (Type C13)
standard connector for the input power and grounding connections. The
grounding terminal on the socket is directly connected to the instrument shell. To
prevent electric shock, the plug must be inserted into a well-grounded socket.
Please use the power cord provided to connect the instrument to the power
source.

SNA5000A Vector Network Analyzer User Manual 4
WARNING: Danger of electric shock!
Disconnected or broken internal or external grounding wires will increase the risk of electric shock. It is
strictly forbidden to destroy the protective grounding wire or safety grounding terminals.
The location of the instrument should be convenient to access the power
supply. To completely power off the instrument, the power cord should be
removed from the power socket of the instrument. When the instrument is idle for
long durations, it is recommended to unplug the power cord from the AC socket.
CAUTION: The RF connector’s shell on the front panel is connected to the instrument’s shell, and then
connected to the earth ground.
Calibration
The recommended calibration cycle is one year. Calibration should only be
performed by qualified personnel.
Cleaning
Only a soft damp cloth without any chemical/corrosive substances can be
used to clean the instrument. Do not clean or use the product in wet
environments. To avoid electric shock, unplug the power cord from the AC socket
before cleaning.
WARNING: Danger of electric shock!
Do not disassemble the instrument. Maintenance must be carried out by qualified personnel only.
Exceptional conditions
Use the instrument only for the purpose specified by the manufacturer. Do
not use if the instrument has visible damage or has endured severe
transportation vibration. If the device is suspected to be damaged, please
disconnect the power cord and contact your local SIGLENT office. To operate the
instrument correctly, all instructions and marks should be read carefully.
WARNING: Use of the instrument for purposes unspecified by the manufacturer may damage the
instrument.

Product introduction
General Description
The SIGLENT SNA5000A series of vector network analyzers have a frequency range of
9 kHz to 8.5 GHz, which support 2/4-port scattering, differential, and time-domain parameter
measurements. The SNA5000A series are ideal for determining the Q-factor, bandwidth, and
insertion loss of a filter. They feature impedance conversion, movement of measurement
plane, limit testing, ripple test, fixture simulation, and adapter removal/insertion adjustments.
The VNAs have five sweep types: Linear-Frequency mode, Log-Frequency mode, Power-
Sweep mode, CW-Time mode, and Segment-Sweep mode. They also support scattering-
parameter correction of SOLT, SOLR, TRL, Response, and Enhanced Response for
increased flexibility in R&D and manufacturing applications.

10MHz Ref Signal
Input
The characteristic impedance of this port is 50 Ω. The detectable input
frequency and power range are 10 MHz ± 10 ppm, -3 dBm to +10
dBm respectively. When there is a 10 MHz external reference signal
on the port, the VNA’s transmitting signal will be locked into this 10
MHz external reference signal. Otherwise, the VNA’s transmitting
signal will be locked into the internal 10 MHz reference signal.
10MHz Ref Signal
Output
This port can output a 10 MHz reference signal so that it can be used
by other equipment. The characteristic impedance, output frequency,
and power range are 50 Ω, 10 MHz ± 10 ppm,-3 dBm to +10 dBm
respectively.
Trigger In
When there is an external trigger signal at the port, the VNA will use
this external trigger signal instead of the internal trigger signal.
