6. Equipment
6.1. Pulse Generator
The surge generator must be capable of producing the Ring Wave as specified by C62.45 Category A and the Combination Wave as specified by C62.45 Category B. (one of the following or equivalent)
• Thermo Scientific EMCPro® PLUS
• Haefely PSURGE 8000 with PIM 110 and PIM 100 Surge Generator, and PCD 1XX Coupling and Decoupling Network
• Teseq NSG 3060-ANSI with CDN 3061 Coupling and Decoupling Network
6.2. Coupling Filter
This device is used to isolate the AC power to the device being subjected to the surge. This allows all the surge energy to be directed to the DUT and not absorbed by the power system. (one of the following or equivalent)
• Not required for Thermo Scientific EMCPro® PLUS
• Haefely PCD 1XX Coupling and Decoupling Network
• Teseq CDN 3061 Coupling and Decoupling Network
6.3. Digital Sampling Oscilloscope
• Tektronix TDS 2022C or equivalent
This device is normally connected to the test connectors of the surge generator to monitor device performance.
6.4. Alternate Waveform Monitoring Equipment
The following test probes (or equivalent) can be used to directly monitor the surge waveforms applied to the DUT.
• Voltage Probe, Tektronix P6015A High Voltage Probe or equivalent
• Current Probe, Tektronix TCP202 or equivalent
6.5. Power Supply: AC or DC, as required by the DUT
7. Set-Up
1. The test equipment shall be calibrated following the manufacturer recommendations. The test equipment shall be allowed adequate warm-up and stabilization time prior to calibration.
2. Determine all configurations to be tested unless directed otherwise. The surge shall be applied to each RF and AC/DC port, unless directed otherwise. The coupling filter shall only be used where AC power is to be present on the port to be surged.ANSI SCTE 81 pdf download.
