5.5 Coaxial connectors used for this product
The coaxial connectors used for this unit is of NoiseKen original design. Use of
other type of connectors may cause electric shock hazards or malfunctions of
the unit. Be sure to use accessories and options supplied by our company.
We have updated coaxial connector specifications to match the output pulse voltage
from the NoiseKen INS. This product (INS-4020/4040) uses a custom design
connector called NMHV which our company designed for 3kV or higher voltage
application. In the market, there are some other types of coaxial connectors similar to
the NMHV. Even when they have similar appearances, they are different from the
NMVH in terms of the inner conductor projection and length of the insulator.
Misconnection of a different type of connector to the NMHV may cause internal
discharges, leading to an unexpected shock hazard or a failure of this product. For
avoiding this kind of misuse, a marking of “NMHV-P-55U” is given on the fringe of the
leading edge of a connector lock. If NMHV connectors have been mixed up with other
types of connectors, discriminate NMHV connectors and use them only. Before
adoption of the NMHV, our company used the other type connector called MHV for
INS-400 series (2kV pulse output) such as model INS-410, INS-420 etc. and their
options. The MHV connector cannot be used for this product (INS-4020/4040) for the
above mentioned reason. The NMHV and MHV connectors are quite different in
appearance and thus they can be easily identified.
When using an external coupling unit such as IJ-4050 or other optional products,
check the connector type and use accessory and cables supplied by our company.

6.2 Pulse generation principle
The main components of the pulse generator circuitry of this unit are coaxial cables,
HV power supply, charging resistor, mercury relay and terminating resistor. The
coaxial cables form a distributed constant circuit consisting of the inductance of the
inner conductor and capacitance of the inner conductor to outer conductor. When a
50Ωresistance terminates this line, it works as a square wave pulse generator.
Pulse widths vary depending on the delay time of the coaxial line (length of the
cable). The proportion of pulse widths to the length is approximately 10 ns per meter.
Pulse waveforms and voltages depend on the relation between terminator resistance
and coaxial cable characteristic impedance. The HV power supply charges up the
capacitance component of the coaxial line through the charging resistor when the
mercury relay is in off status. The stored energy is discharged when the mercury
relay contacts turn on, generating a HV square wave pulse across the terminating
resistor. The injection unit couples this pulse through a capacitor to a EUT LINE.
Also provided is a Decoupling circuit consisting of an inductor and capacitor, working
as a high impedance circuit when seen from the injection point. This enables to
effectively couple the interference signals to the EUT and to reduce them to leak into
the power supply side (LINE IN).

6.3 For perfect matching
Pulse waveforms and amplitudes are dependent on the value of a termination resistor being
connected to the PULSE OUT terminal. The figures and equation shown below describe these
relations. To generate square wave pulses, this unit adopts a 50Ω(strictly, 53.5Ω), equal value to
the characteristic impedance of the coaxial cables.

Pulse repetition in
VARIABLE mode 10~999ms(INS-4020) at 1ms step 16~999ms (INS-4040) at 1ms step
(Note 1) The output voltage display reads the correct pulse voltage only when the
built-in terminating resistor terminates the coaxial line (at the PULSE OUT)
When the terminating resistor is disconnected from the test circuit, the
actual pulse amplitude is approximately 1.8 times of output voltage display
reading and its waveform no longer square (damped). An automatic
correction for the voltage indicator is available by means of turning on the
unit with a different key operation. For details, refer to Section 9.10.
(Note 2) The fastest repetition of generated pulses (VARIABLE) is 10ms for INS-4020
and 16ms for INS-4040. This comes from different construction of the two
types of mercury relay.
