GLN-5040A User Manual
OVERVIEW
The GLN-5040A Two Line V-Network is used for
EMI testing. It provides a stable impedance for
the EUT terminals and the reference ground
within the conducted emissions range. The GLN5040A also isolates the unwanted network signals
from the power supply unit and only couples the
disturbance voltage of the measured device to the
receiver. The product's performance is in
compliance with the standard requirements of
CISPR16-1-2 for V-networks with a simulated
impedance of 50μH + 5 Ω) || 50 Ω in the
frequency range of 9kHz to 30MHz. It uses
standard BNC output connector with 50 Ω output
impedance to match any measurement devices
such as receivers and spectrum analyzers. The
product is equipped with an artificial hand
function that simulates a handheld type
measurement, a 9kHz and 150kHz high pass
filter selection function that allows the product to
select the correct filters according to the relevant
standard. The GLN-5040A is also suitable for
signal phase device conduction (disturbance
voltage) measurement. Due to design principles,
there may exist a great deal of leakage current. It
is recommended that the unit is grounded when
used, and if necessary, it should also be used
with an isolation transformer. You may use the
GIT-5060, which has an output capacity of 900VA,
meeting the requirements of most test equipment.

1. Artificial mains network must use the isolation
transformer to isolate to ensure personal safety.
2. The GLN-5040A must be grounded to ensure
personal safety, especially when there is no
isolation transformer connected. If the GLN5040A is not grounded it may lead to serious
electrical shock.

Procedure
1. Ground the GLN-5040A with the testing
receiver ground wire.
2. Connect the isolated transformer and the GLN-
5040A two line V-network.
3. Connect to the EUT; please place the equipment
with the reference to the above schematic
diagram.
4. Connect the GLN-5040A interference signal
output terminal to the EMI receiver input
terminal.
5. Select the correct filter for the testing standard.
6. Connect the GLN-5040A to the isolation
transformer, which is connected to the power
grid, and power on to test.
7. Use the phase line switch on the GLN-5040A to
select different phase lines during the test.
Note
When using the equipment, don't open the case,
don't in a humid, explosive or inflammable
environment. Please ensure the equipment
surface is dry and clean before use.
The maximum voltage should be under 50V
when using the AC power supply.
Please read the user manual carefully before
use to become familiar with the safety the
requirements and to test correctly.
It is recommended to use an isolation
