User Manual Safety Follow these instructions to keep the probe operating in a correct and safe condition. Observe generally accepted safety procedures in addition to the precautions specified here. The overall safety of any system incorporating this accessory is the responsibility of the system owner. Symbols These symbols appear on the probe and accessories or in this manual to alert you to important safety considerations. -
Page 6: High Voltage Safety
Do not remove the probe’s casing. Touching exposed connections may result in electric shock. Do not disassemble the probe or remove inside parts. Refer all service to Teledyne LeCroy personnel. Use only indoors within the operational environment listed. Do not use in wet or explosive atmospheres. - Page 7 User Manual Maximum safe handling limits for common mode voltages between the probe head and tips with respect to earth ground. WARNING: Maintain 1 m (~40 in) safe clearance of the probe head and tip in all directions when connected to an energized circuit. Place the oscilloscope and any equipment you need to access at least 1 m from the circuit and probe head.

Page 11: Dl-Iso Probe System
User Manual DL-ISO Probe System Standard Parts DL-ISO Probe The probe head contains a frequency modulating optical transmitter and receiver integrated with a high-performance electrical amplifier. It is connected to the control module by an integrated fiber- optic cable. The control module utilizes the ProBus interface to communicate tip attenuation value and proper voltage scaling to the oscilloscope. -
Page 12: Probe Tips (At Least One Required)
DL-ISO High Voltage Optically Isolated Probes Probe Tips (at least one required) Probe tips are sold separately from the probe itself, but at least one tip is required for proper functioning. Tips can be stored in a compartment in the soft carrying case. The 2 Vpp through 200 Vpp MMCX Tips are high-quality coaxial attenuating tips that reject unwanted noise while terminating into standard MMCX connectors. -

Page 21: Operation
User Manual Operation Note: Operating the probe requires MAUI firmware version 9.9.x.x or higher. To confirm the version, choose Utilities > Utilities Setup from the oscilloscope menu bar, then open the Status tab. Connecting the Probe to the Test Instrument Connect the probe to the oscilloscope through the ProBus input. -
Page 22: Operating With An Oscilloscope
DL-ISO High Voltage Optically Isolated Probes Operating with an Oscilloscope When the entire DL-ISO, including the attenuating tip, is connected to a Teledyne LeCroy oscilloscope, the displayed scale factor and measurement values are adjusted to account for the effective gain of the probe. The oscilloscope will set the proper probe attenuation according to the information received from the tip, while the oscilloscope probe control functions are activated, and probe gain and offset can be controlled through the oscilloscope. - Page 23 User Manual Auto Zero The Auto Zero procedure corrects for DC offset drifts that naturally occur from thermal effects in the probe system. DC offset drift is independent of probe tip connected, but it is affected by oscilloscope gain setting and ambient temperature. DL-ISO Full Scale Range (FSR) is calculated as: 8 x Vertical Gain Sensitivity For example, at 100 mV/div, FSR = 100 mV/div x 8 = 800 mV.
- Page 24 DL-ISO High Voltage Optically Isolated Probes The probe dialog will indicate when the probe has a valid calibration (green “√ Pass”): Calibrations are not cached. If the probe was previously calibrated at one temperature then re- calibrated at another before returning to the first temperature, the Precision Gain Calibration will have to be repeated.

Page 25: Performance Verification
User Manual Performance Verification DL-ISO probes shipped from Teledyne LeCroy are tested and adjusted to meet the Gain Accuracy specification. This procedure can be used to verify the performance of an DL-ISO. Some of the test equipment used to verify the performance may have environmental limitations required to meet the accuracy needed for the procedure. -
