Trigger and Interlock Terminals
The M9602A/M9603A has the following terminals for the trigger source or output and the interlock circuit status detection.
The M9602A/M9603A has a 6-pin terminal block on the front panel. The pin assignment of the terminal block is shown in
Figure 1-1 . You can connect these
terminals using a connector-terminal block furnished with the M9602A/ M9603A and ferrule terminal cables such as Keysight PX0101A-001 or PX0101A-002 BNC to ferrule terminal cable.
Trig 1 and Trig 2 External trigger 1 and 2 terminals
These terminals are used to make synchronization with other modules or instruments. You can specify the direction (input/output), the polarity (positive/ negative), and the pulse width of the trigger signal. The output trigger is push-pull, and the trigger level is 0 V to 3.3 V at high impedance. The input trigger should be the TTL level.
Intlk Interlock terminals
These terminals are used to connect an interlock circuit which is installed in your test fixture or shielding box. The interlock circuit can be created by using two mechanical switches and wire as shown in
Figure 1-5 . If the interlock terminals are
opened or the interlock circuit is opened, the M9602A/M9603A output voltage is limited to 42 V or less as you specified. If you set the voltage limit to 0 V, the interlock function will be the same as inhibit control.
For more details, see
“Installing Interlock Circuit” on page 31
.
Do not connect the interlock terminals to anything other than the interlock circuit. Applying current or voltage to the terminals may damage the
M9602A/M9603A.
Dangerous voltage, instrument maximum output voltage may appear at the High force, High sense, and Guard terminals if the interlock terminals are closed or the interlock circuit is closed.

This section describes how to connect a device under test (DUT) to the
M9602A/M9603A, and includes the following descriptions.
“2-Wire Connection or 4-Wire Connection”
To avoid touching the end of the extension cable or the terminal area with the
DUT, cover over the conductors with insulator. Also it is important to protect the terminal area by using the grounded shield cover and such.
To prevent electrical shock and DUT damage, do not connect or disconnect the
DUT while the instrument is applying voltage or current.
When you touch the DUT after the measurement, devise a countermeasure of residual charge and heat to prevent electrical shock and burn. Use gloves and any tool. Also have enough time for discharge and radiation.
Afin d'éviter de toucher l'extrémité du câble d'allongement ou l'aire de la borne avec l'appareil mis sous tension (MST), couvrez les conducteurs avec l'isolant. En outre, il est important de protéger la zone de la borne en utilisant le couvercle d'écran à la mise à terre, ou tout autre élément.
Afin d’éviter toute décharge électrique et dommage MST, ne branchez ou déconnectez pas la sortie MST alors que la source de sortie est appliquée.
Lorsque vous touchez le MST après la mesure, élaborez une contre-mesure de la charge résiduelle et du chauffage afin d'éviter tout choc électrique et toute brûlure. Utilisez des gants et des outils. Prévoyez également du temps pour la décharge et la radiation.
Set the instrument output off when changing the connections. If not, the DUT may be damaged.

Connecting a DUT
Connecting the interlock circuit
The M9602A/M9603A provides an interlock function to prevent the user from receiving an electrical shock from high voltages over the limit. The limit is programmable within 42 V. If the interlock terminals are open, the M9602A/
M9603A cannot apply a high voltage over the limit.
For high voltage measurement, connect the interlock terminals to the interlock circuit as described in
“Installing Interlock Circuit” on page 31
.
Generally, environmental conditions, such as electromagnetic environment, have a negative impact on the performance of the instrument. Use coaxial cables and shielding technique to minimize the impact.
2-Wire Connection or 4-Wire Connection
When connecting a device under test (DUT), you can choose the connection type either the 2-wire connection or the 4-wire connection.
If you want to simplify the connection, use the 2-wire connection by connecting the force terminals only, while the sense terminals remain open.
To make the 4-wire connection, well known as Kelvin connection, use both force and sense terminals. Connecting the force and sense lines together at the terminal of the DUT minimizes the measurement error by the residual resistance of the test leads or cables. This connection is effective for low resistance measurements and high current measurements.

Floating
When the M9602A/M9603A is shipped from the factory, the Low force terminal is connected to the frame/chassis terminal by the short bar. The short bar must be connected to perform the grounded measurement.
If you want to perform the floating measurement or if you want to connect another instrument’s ground to the Low force, remove the short bar, and leave the terminals open. Then use the Low force terminal on the HF or HS connector to connect the other instrument.
For the floating measurement, do not apply voltage over 40 V to the Low force terminal. V floating
, the voltage between Low force and the frame/chassis ground, is limited to 40 V. Failure to heed this caution may result in damage to the
M9602A/M9603A.
Do not apply current or voltage to the frame/chassis terminal. Doing so will damage the M9602A/M9603A.
To prevent electrical shock, do not touch any of measurement circuit at any time while a floating measurement is in progress. Also use accessories that comply with IEC 61010-031. All terminals and the extended conductors must be isolated by using insulation caps, sleeves, etc.
Afin d’éviter toute décharge électrique, ne touchez aucune mesure de circuit à tout moment lorsque la mesure de flotte est en cours. Utiliser également des accessoires qui sont conformes à la norme IEC 61010-031.

Connecting a DUT
Guarding
Figure 1-4
Guarding reduces the leakage current between the instrument and a DUT. This is important when you perform low current measurements.
The overview of the guard technique for the grounded measurement is shown in
. The guard shield is necessary to prevent the leakage current in the measurement environment including extension cables, test fixtures, shielding boxes. It is important to use a triaxial cable such as Keysight PX0102A-001 Low noise triaxial cable (1.5 m). The buffer amplifier keeps the potential of the Guard
(inner shield of triaxial cable) at the same potential as the High force (core), so that the current does not flow between the core and the inner shield. Therefore ideally, the current measured by the instrument is the same as the current at the DUT terminal because there is no leakage current. For several connection examples such as the floating measurement, refer to the configuration guide.

Low force signal comes from the outer shield of the HF connector. In the ground measurement, the outer shield of the triaxial connector must be electrically isolated from the shield of your test fixture or shielding box. Do not connect the outer shield to anything other than the low terminal of DUT.
Never connect the guard shield to any output, including the frame/chassis ground or any other guard terminal. Doing so will damage the M9602A/M9603A.

The output off mode is ignored if an emergency condition such as interlock open and over voltage is detected. Then the output voltage is immediately set to 0 V, and the output switch is set to off.
Interlock
The interlock function is designed to prevent electrical shock when you touches the measurement terminals and also to prevent DUT damages caused by undesirable high voltage.
The M9602A/M9603A module cannot apply high voltage over the interlock threshold voltage level when the interlock terminals are open. The interlock threshold voltage level is programmable within 42 V, and the default value is
42 V. Set the threshold voltage to the voltage you think still safe. If the threshold voltage level is set to 0 V, the interlock function is same as inhibit control.
To apply high voltage greater than 42 V, the interlock terminals should be connected to an interlock circuit. See
“Installing Interlock Circuit” on page 31
.
The interlock function works as follows.
•
•
•
When the interlock terminals are open, the maximum output is limited to the threshold voltage level.
When the interlock terminals are shorted, the module can apply the maximum output voltage of the channel.
If the interlock terminals are opened in a high voltage condition over the threshold voltage level, the output voltage is immediately set to 0 V, and the output switch is set to off.
Keysight M9602A/M9603A Startup Guide, Edition 3 43
Function Overview
Protection from Emergency
The protection from emergency is effective in preventing damages to the module due to high temperature, over voltage, over current, or other conditions. The
M9602A/M9603A provides two types of protection. One is an emergency shutdown and the other is an immediate output-off.
When the over temperature or the system error such as power supply failure or internal communication failure is detected, the emergency shutdown occurs. The module is powered off and two LED indicators turn red.
When the emergency including the over voltage, over current, and interlock open is detected, the output is automatically turned off; the output voltage is immediately set to 0 V, the output switch is set to off, and the “Status” LED indicator turns off. If the emergency condition continues for a certain period of time after the immediate output-off, the emergency shutdown occurs.
If the emergency shutdown occurs, perform the self test. See “Self Test” on page
.
