1. PURPOSE
1.1. Portable signal generators ARINST ArSiG-S and ARINST ArSiG-R are designed to generate
high-frequency signals in the range 1-6200 MHz. The devices are capable of sweeping the output signal,
both in frequency and in level. The generators have the ability to use an external highly stable signal
source as a reference.
1.2. Generator ARINST ArSiG-S is a generator of sinusoidal signals in the entire operating frequency
range. The ARINST ArSiG-R generator generates rectangular signals in the frequency range up to 3000
MHz. In the range from 3000-6200 MHz, the device generates sinusoidal signals.
1.3. Generators play an important role in electrical and radio measurements. They are used to gener-
ate test signals for the development and debugging of various devices: amplifiers, filters, receiving and
transmitting paths, when measuring and analyzing antennas.

6. DESCRIPTION AND OPERATION PRINCIPLE OF THE DEVICE
Signal generators ARINST ArSiG-S and ARINST ArSig-R are based on a phase-locked loop (PLL)
synthesizer. The output signal is generated by dividing the set frequency of the voltage controlled oscilla-
tor (VCO). Comparing the obtained value with the frequency of the reference oscillator and adjusting the
VCO with a voltage proportional to the obtained difference. Structural diagrams of generators are shown
in Figures 6.1 and 6.2.
Generator ARINST ArSiG-S is a generator of sinusoidal signals in the entire operating frequency
range. Structurally, it is a generator with a support. The basic principle of the formation of the output sig-
nal in the low-frequency region of the frequency range is the multiplication of the signals of the two gen-
erators using a mixer. The mixer output is filtered to suppress higher harmonics and isolate the funda-
mental frequency. In the second subband, the signal from the synthesizer output is fed to the low-pass
filter to suppress the higher harmonics of the generated signal. In the third subband, the output of the
VCO of the frequency synthesizer is used to generate the output signal. The output of the VCO is a fun-
damental frequency with suppressed harmonics, so there is no additional filtering. Then the generated
signal is fed to a power amplifier. The amplified signal is fed to the output connector. Also, with the help of
a power coupler, the output power is measured and with the help of an automatic adjustment loop, the set
level is maintained.

Figure 6.1 - Block diagram of the ARINST ArSiG-S signal generator
The ARINST ArSiG-R generator produces rectangular signals in the frequency range up to 3 GHz.
From 3 GHz, the output of the VCO of the frequency synthesizer is used to generate the output signal.
Thus, the output signal is sinusoidal. Then the generated signal is fed to the power amplifier. The ampli-
fied signal is fed to the output connector. Also, with the help of a power coupler, the output power is
measured and with the help of an automatic adjustment loop, the set level is maintained.
Figure 6.2 - Block diagram of the ARINST ArSiG-R signal generator
Both generators use a high-stability temperature-compensated oscillator with low phase noise as a ref-
erence frequency source.

you to save a lot of battery power. If you do not need to turn off the display of the device after a certain
period of time, select the parameter Never. Setting the time of automatic shutdown of the device screen
is made by "scrolling" the values.
The device continues to work after the screen is turned off, the STATUS indicator is on. Tap anywhere
on the screen to turn it on.
10.8. External trigger control
To synchronize measurements using several instruments, use the SYNK I / 0 signal connector located
on the right panel of the generator (Fig. 5.1). The connector is used both as an input and as an output of
the synchronization pulse.
10.8.1. Enter the additional Settings menu by pressing the button on the device screen (Fig.
10.9). By default, the External trigger control option is disabled Disabled.
10.8.2. To use the generator as a master device and send a control pulse from the SYNK I / 0 con-
nector, select the Master mode in the drop-down menu. If the generator is used as a controlled device
and must receive a control pulse from the master device on the SYNK I / 0 connector, select the Slave
mode from the drop-down menu.
The maximum input voltage applied to the SYNC I / O port is + 3.3V.
10.9. Using an external reference frequency source
The device can use both an internal and an external signal as a reference signal. The external refer-
ence signal is fed to the REF IN input located on the right panel of the generator (Fig. 5.1).
10.9.1. Enter the additional Settings menu by pressing the button on the device screen (Fig.
10.9). Switching between the external and internal sources of the reference signal is performed by the
“slider” of the External oscillator. Set the frequency of the external reference signal.
The maximum allowable power of the external input signal is +13 dBm. It is recommended to
apply a signal with a power of no more than +10 dBm to the input of the device.
10.10. Output frequency correction
The output frequency may differ slightly from the output frequency of the reference instrument. Adjust
the generator output frequency to match the frequency of the reference instrument.
10.10.1. Enter the additional Settings menu by pressing the button on the device screen (Fig.
10.9). The input signal frequency adjustment mode is enabled by the Int. osc. correction slider. Set the
actual frequency of the output signal. The difference between the current frequency value and the input
reference value should not exceed ±0.1% (1000 ppm) of the current frequency. Otherwise, a message
appears stating that this adjustment cannot be applied.
10.11. Offset of the output signal level value
Offsetting the value of the output signal level allows you to compensate for the effect of a device con-
nected to the generator output and changing the output power level.
The power level offset option allows a constant value to be applied to the displayed level, thereby
compensating for loss or gain from the connected device. In this case, the displayed power level will cor-
respond to the actual power level at the output of the connected device.

10.11.1. Enter the additional Settings menu by pressing the button on the device screen (Fig.
10.9). The power level offset of the output signal is enabled by the slider Level offset. Set the power level
offset value. When connecting an attenuator, use negative offset values, such as -10, -20, etc., and when
connecting an amplifier, use positive values, such as +10, +20, etc.
10.11.2. The value of the power level offset is shown in parentheses in the power field of the device
(Figure 10.10).

11. CARE AND MAINTENANCE
11.1. General care of the device
11.1.1. Maintenance consists in maintaining the device in working order, regularly carrying out preven-
tive maintenance.
11.1.2. Wipe the connectors of the test ports with a soft cloth or a brush dampened in rectified ethyl
alcohol, not allowing alcohol to get on the surfaces of dielectrics.
11.1.3. Clean the body of the device from dirt with a soft cloth dampened with soapy water or wet
household wipes. The penetration of liquids into the housing of the device is not allowed!
Do not use solvents based on alcohol or petroleum products to clean the screen and body
of the device! These liquids can damage the outer coating of the screen and the case of the prod-
uct.
11.2. Charge the battery
11.2.1. It is recommended to use a stabilized power supply with an output voltage of 5V and a current
of at least 1000 mA to charge the battery.
The device has an intelligent system for determining the maximum charging current depending on the
available power source. When the charger is connected, the maximum charging current is automatically
determined. To reduce the charging time of the built-in battery, it is recommended to use industrial power
supplies (chargers) with a maximum output current of 3 A as a charger.
11.2.2. Соедините USB-кабелем из комплекта поставки Mini-USB разъём прибора (11) с USB-
разъёмом блока питания или USB-портом ПК.
11.2.3. The CHARGE indicator (10) lights up while the battery is being charged. The battery charging
process will take about 3.5 hours. When charging is complete, the CHARGE indicator (10) will turn off.
The device is allowed to operate while the battery is charging, provided that the power supply is capable
of providing an output current of at least 1500 mA. If the charger or the USB port of the PC is not able to
provide the current required for the operation of the device and charging the battery, the device will auto-
matically reduce the charging current until the battery is completely charged.
11.3. Battery replacement
11.3.1. After a certain period, the capacity of the Li-Ion battery is reduced, and long-term use of the
device without recharging becomes difficult.
11.3.2. Replacing the battery is necessary when the following symptoms occur:
the battery charges very quickly and discharges very quickly;
the battery charges for a very long time (more than 10 hours);
the battery does not accept charge;
the device does not turn on offline (with the cord disconnected from the charger).
11.3.3. To replace, you must purchase a new Li-Ion battery with an operating voltage of 3.7 V, a ca-
pacity of at least 5000 mA and dimensions of not more than: height 7 mm, length 90 mm, width 60 mm.
When purchasing and installing a battery with a capacity other than the one installed by the device
manufacturer, it is necessary to take into account the fact that the battery charging time will also change
up or down.
Attention! When using a battery of another capacity, the correspondence of the displayed
charge level of the battery on the device screen to the real value is not guaranteed.
Attention! To replace the battery, you will need to disassemble the device. Ensure that you
have the necessary tools, knowledge, and qualifications sufficient to carry out an independent
repair of the device. With a lack of experience and qualifications, contact specialists with relevant
qualifications.
