Return the instrument to Aemulus for service and repair to ensure that safety features are maintained. WARNING The WARNING heading explains hazards that might occur if an operating procedure, practice, or the like that, if not correctly performed or adhered to might result in personal injury or death. Always read the associated information very carefully and make sure the indicated information is met before performing the indicated procedure. CAUTION The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may invalidate the warranty. AEMULUS 2 AM450e User Manual B. Identification and Discouragement of Hazardous Applications CAUTION Main Power WARNING Instrument Cables / Connectors WARNING Instrument Output Ensure that the mains power is turned off before plugging or removing the PXI module into or from the chassis. Make sure the power cord is plugged properly to the chassis before applying power. The chassis that carries the instrument has to be plugged into a grounded (earthed) power outlet. By not doing so, it will defeat the power cord safety ground feature. Ensure that the power is removed from the product before connecting/disconnecting the cables to the product connectors. Inspection of the connecting cable and test leads for possible wear, cracks, or breaks must be done before each use. Make sure the cables used for the product are rated to the specified voltage and current level. Extreme caution is to be practiced when a shock hazard is present. Lethal voltage may be present on cable connector jacks. When power is applied to the circuit under test, do not touch the product and test cables or test leads. Do not touch the connector jacks or cables when the output of the product is turned on.

AEMULUS 13 AM450e User Manual Section 3: Brief Technical Description AM450e is a source-measure unit (SMU). 3.1 Basic Operation AM450e is more than the just a power supply. It is fast-response, read-back voltage and current sources with high accuracy measurement capabilities. It is designed for circuit and device evaluation where a DC signal must be applied to a device under test (DUT) and the response to that signal measured. AM450e is capable of multi-quadrant operation, such as acting as a positive DC source or as a sink (Load). AM450e can be set up to function as a voltage source/current monitor, current source/voltage monitor: 1. Source Current, Measure Voltage / Current a. This configuration turns AM450e into high-impedance current source b. The voltage developed is limited by compliance setting c. If current is 0A, AM450e becomes a voltmeter 2. Source Voltage, Measure Current / Voltage a. This configuration turns AM450e into low-impedance voltage source b. Current flow is limited by compliance setting Figure 3: Typical Operation AEMULUS 14 AM450e User Manual To prevent over-voltage or over-current damage to the device-under-test (DUT), several levels of output protection, termed COMPLIANCE, is incorporated. Maximum specifiable compliance depends on the voltage or current range at which the source channel is operating. The specified compliance is valid for positive and negative values, regardless of the polarity specified in the COMPLIANCE field. For example, specifying a current compliance of 40mA, is valid for +40mA and –40mA, output current more that ±40mA are not possible. If a source channel reaches compliance during measurement, this indicates an error in the operation. Example: 1. AM450e is set to voltage source/current monitor mode; compliance of 1mA; output load is a 1kohm resistor 2. If source voltage is 5V, the current that should flow through the resistor is 5V/1k=5mA 3. Due to compliance of 1mA, the source channel turns into a constant current source of 1mA. This yields a voltage of 1V across the resistor The measurement result is the average value of all samples taken for nth number of power line cycle (PLC). For example, if the line frequency is set to 50Hz (period is 20ms), then 1 PLC equals to 20ms. The measured data is a resultant of averaged of raw samples captured by ADC on AM450e for 20ms. NOTE The NPLC setting of an instrument allows adjustment of the tradeoff between speed and accuracy. The greater the number of power line cycles, the greater noise rejection and better resolution the signal value will be. AEMULUS 15 AM450e User Manual 3.2 SMU Connection There are 5 leads per channel: 1. 2. 3. 4. 5. Guard Force-High Force-Low Sense-High Sense-Low Force-High and Force-Low outputs are where voltage and current are generated during source or sink operation. Sense-High and Sense-Low outputs are high impedance paths. Connect these lines as close to the DUT terminal as possible for more accurate voltage source or measure operations. Presence of Sense lines at the DUT terminals is known as 4-wire, remote-sense, or Kelvin operation. For high power device testing, there can be significant voltage drops in test leads due to the high current flow. Using remote sense becomes very critical to ensure accurate source and measure operation. Advantages of using 4-wires measurement: 1. It eliminates the resistance of your interface cabling 2. Lengthy wires would not be an issue anymore 3. It allows measurements on lower resistance values than 2-wire testing Guard terminal is a low impedance output that is very close to the signal voltage on the ForceHigh output. Typically, the Guard output is kept within 2mV on the Force-High output. AEMULUS 16 AM450e User Manual Figure 4: Typical 5-Wire Connection AEMULUS 17 AM450e User Manual 3.2.1 Guard Terminal The purpose of Guard is to reduce current leakage into sensitive node, from SMU output connector all the way to the DUT terminal, via cables, PCB, and/or test fixture. This current leakage can affect the measurement results if not being taken carefully. Measurement test time can become very long in order to fully charge up the leakage current caused by the parasitic paths, before actual test results of the DUT can be taken. There are known current leakage issues from Force-High to Force-Low conductors in a coaxial cable. Imperfect insulators between center and outer (shield) conductors result in current leakage. In this case, guarding can be used to eliminate parasitic capacitances. Figure 5: Coaxial Cable Connection Guard terminal can effectively solve the current leakage issues in a triaxial cable. For triaxial able, there is an additional layer (driven guard) that exactly tracks the voltage sweep (force line) which eliminates cable charging since the inner and outer parts of the cable are always kept at the same potential. It eliminates any noise since the driven guard is connected to a separate low noise amplifier inside the SMU. Figure 6: Triaxial Cable Connection AEMULUS 18 AM450e User Manual WARNING Never short the guard and force line together because it will defeat the effect of the driven guard. AEMULUS 19 AM450e User Manual 3.2.2 Floated Output AM450e is a floated SMU. This means it can be cascaded in series to produce higher voltage source, or connected in parallel to produce higher current source. 3.3 External High Current Module By adding an external module, AM450e can be used for pulse generation at 30V and 1A (pulse) range. This module needs with external 15V/2A power supply. AEMULUS 20 AM450e User Manual Section 4: Maintenance 4.1 Cleaning Before doing any cleaning to the product, switch off the chassis and disconnect it from main power supply. You can wipe the front panel of the module using a soft cloth moistened in water, taking care not to wet the connectors. Do not use aerosol or liquid solvent cleaners. You can use a handheld vacuum cleaner to remove any accumulated dust on the product, if necessary. CAUTION Be careful NOT to be in direct contact with any circuits on the product to prevent any damages. Contaminants such as oils and salts from the human skin can affect the performance of the product. Comply with good ESD practice when handling the product during cleaning. 4.2 Calibration Electronic components tend to drift over time. Environmental changes, operation stresses and aging increase the measurement uncertainty. Periodic calibration is required to ensure the accuracy of the instrument. The recommended calibration interval for the product is 6 months. 4.3 Servicing There are no user-serviceable parts in the product; if any attention is needed, return it to instrument manufacturer.
