Page 8: Operating Information
OPERATING INFORMATION FEATURES The Model 106H plug-in module provides a 1064 nm laser diode optical output source for the Model 6040 Universal Pulse Generator, The 106H operates only in the Pulse Mode of the 6040 mainframe. It supplies flat-topped pulses with fast rise and fall times and adjustable Peak level. Baseline level is fixed at zero (no light output). -
Page 9: Safety Precautions
2-1 gives the default settings for the 106H module. The Quick Test procedure for the mainframe may be applied to the 106H by selecting the Pulse Mode and following the test sequence using the module's LIGHT OUT connector and an optical detector in place of the mainframe's PULSE OUT. -
Page 10: Rear Panel Description
OUT is at zero volts (see Figure 1-1). Rear Panel Description The rear panel of the 106H module has a mounting screw (for installation into the mainframe), one 40-pin edge connector, and one SMA connector. The 40-pin connector allows the 6040 mainframe to control and communicate with the module and also supplies the power to the module. -
Page 11: Mainframe Operation
This section presents information on how to operate the Model 6040 Universal Pulse Generator with the Model 106H optical module installed. Only the details that are specific to the module are described. For an overall description of how to use the mainframe with plug-in modules, please refer to the 6040 manual. - Page 12 LEVEL Menu Peak {MODE} The Mode menu for the 106H has only the Pulse Mode available In this Mode, flat- topped pulses of specified Width, Peak level and Delay are produced. {TRIG} The Trigger source and parameter menu has five menu items Single Cycle, Internal Trigger (and Rate), External Trigger (and Threshold), and External Trigger Slope.

Page 13: Remote Programming
Consult the 6040 manual and the above section for details on controlling the instrument with remote programming. The Module Status command, the only command that is specific to the module, is not used with the 106H and will return an undefined value. -
Page 14: Section 3 Theory Of Operation
SECTION 3 THEORY OF OPERATION General CIRCUIT DESCRIPTION Module Interface The module is controlled by the mainframe via signals received on the 40-pin connector, P8 (see Table 3-D. Signals QADO-QAD7 are multiplexed with data and address. QA8-QA12 are no multiplexed address lines. -
Page 15: Laser Drivers
THEORY OF OPERATION Z8, the PPI, is used to control the output level and width selection. PA0-PA7 control Z7 (an 8-bit DAC) which sets the power level of the light pulse. Port B is not used. PC0-PC3 are used to select one of four different preset widths, and PC4 is a software disable. - Page 16 THEORY OF OPERATION The CL2A and CL3A clipping lines are normally open and store very little energy. Even if they became shorted, the current is limited by R40 to a level well below the laser's maximum rating. As an additional precaution, the high voltage supply itself (PSD is only capable of 2 mA.

Page 17: Section 4 Maintenance And Calibration
It is recommended that the calibration of the 106H module be verified every 12 months. The instrument requires no warm up period exceeding that of the 6040, for which ten minutes is suggested. -
Page 18: Procedure
MAINTENANCE AND CALIBRATION PROCEDURE WARNING: Do not attempt to adjust R3. This control has been factory set for accurate wavelength. If the laser is defective, return the module to the factory. Set the displayed Peak level to 15 mW. Select Internal Trigger with a 2 kHz rate. Set the Width to 25 ns (width Set TP-A (Z13-l) to- 0.3V with R91.
