1.2 Electrical Safety
Precautions for electrical safety of the instrument:
1) Before the instrument is powered on, the actual supply voltage should match the supply voltage marked on the
instrument.

Tel: [phone] Email: [email protected]

2) According to the power requirements of the real panel of the instrument, a three-core power cord should be
adopted while ensuring reliable grounding of the ground wire during operation. Either floating ground or poor
grounding may cause damage to the instrument and even cause injury to operators.
3) Do not damage the power cord, otherwise electric leakage will be caused, resulting in damage to the
instrument and even injury of the operators. If an external power cord or extension socket is used, it should be
checked before use to ensure electrical safety.
4) If the power supply socket does not provide an on/off switch,to cut the power of the instrument, you can just
directly unplug the instrument, and therefore, it should be ensured that the power plug can be inserted or
drawn conveniently.
5) Do not use damaged power cords. Before connecting the instrument to the power cord, check the integrity and
safety of the power cord, and properly place the power cord to avoid the impact due to human factors, such as,
too long power cord that may trip the operator.
6) Keep the socket clean and tidy, and ensure the plug and the socket in good contact and reliable engagement.
7) Neither the socket nor the power cord can be overloaded, otherwise fire or electric shock will be caused.
8) Unless otherwise allowed, do not open the housing of the instrument, which may expose internal circuits and
devices of the instrument and cause unnecessary damage.
9) If the instrument needs to be fixed at the test site, a qualified electrician is required to install the protective
earth wire between the test site and the instrument first.
10) Take appropriate overload protections to prevent overload voltage (caused by lightning, for instance) from
damaging the instrument or causing personal injury.
11) When opening the housing of the instrument, do not place objects not belonging to the interior of the
instrument, otherwise, short circuit, damage to the instrument and even personal injury may be caused.
12) Unless otherwise stated, the instrument has not received any waterproof treatment, so keep the instrument
from contacting with liquid to prevent damage to the instrument or even personal injury.
13) Do not place the instrument in an environment where fog is easily formed, for example, moving the instrument
in a environment where cold and heat are in alternation, where water droplets formed on the instrument may
cause electric shock and other hazards.
1.3 Operation Precautions
1.3.1 Power Check
The S1132 multi-standard signal generator can be powered by 110V-220V alternating current; before turning it on,
you must confirm that the ground wire of the AC power source is reliably grounded before inserting the plug of the
power cord into a standard three-pin socket. Never use a power cord without a protective ground. Floating ground

or poor grounding may damage the signal generator and even cause personal injury. In order to prevent or reduce
the mutual interference caused by multiple devices through the power supply, especially the spike interference
generated by high-power devices may cause damage to the instrument hardware, it is best to use a 220V/110V AC
stabilized power supply to power the adapter.

1.3.2 Initial Power-up of the Signal Generator
1) Turn on the strong power switch at the back of the instrument, and the fan starts to run;
2) Turn on the front power control switch, and it takes about 30 seconds to start the instrument;
3) After the instrument is started up, it needs to be warmed up for 20 minutes before testing.

This chapter introduces the function and usage of the S1132 signal generator through examples. The contents of
this chapter are as follows:
Continuous Wave Signal
Sweep Signal
Analog Modulation Signal
Digital Modulation Signal
Pulse Modulation
LF Signal
Up-conversion Function

3.1 Continuous Wave Signal
The most common output signal of a signal generator is the continuous wave limit signal. In the following example,
we use Agilent N9020A spectrum analyzer to measure the CW output signal information of S1132 signal generator
(with frequency of 1GHz, amplitude of -10dBm).
Operation steps:
1. Instrument connection
Use a coaxial cable to connect the signal output end of the signal generator to the RF input port of the N9020A
spectrum analyzer.
2. Parameter setting
(1) Reset the signal generator
—Press【Preset】button
(2) Parameter setting
