OPERATING INFORMATION
FEATURES
The Model 106C, 155 and 130 plug-in modules provide 1064nm, 1550 nm and 1310 nm optical output
sources for the Model 6040 Universal Pulse Generator. Accurate and adjustable outputs are available for
all of the four modes in which the 6040 mainframe can operate.
In Pulse Mode operation, the 106C/155/130 supplies flat-topped pulses with fast rise and fall times and
independently adjustable Peak and Baseline levels. The timing for these pulses may be supplied in a
number of ways.
A delayed pulse of adjustable width may be generated by the mainframe. This delay can be specified
with respect to an internal trigger occurring at a selected repetition rate or with respect to an externally
supplied trigger signal (TRIG IN). In addition, Single Cycle operation allows the user to trigger the
instrument manually, using a pushbutton (or using remote programming). In each case a trigger out
signal (TRIG OUT) is provided by the 6040 for reference (see Figure 1-1). Double Pulse operation,
producing both an initial and delayed pulse put of the same jack may be selected for any trigger choice.
For all of these timing options, the mainframe supplies electrical output pulses (PULSE OUT) coincident
with the module's optical output (LIGHT OUT).
External Drive operation is also available in the Pulse Mode. This allows a drive signal, supplied by the
user to the module's front panel (EXT DR), to generate the optical pulses directly. The occurrence and
duration of each light pulse will correspond to that of each pulse in the external drive signal: when the
EXT DR pulse goes high, the light pulse goes to the Peak value. Peak and Baseline output levels remain
specified by the mainframe (as well as the threshold level for the external drive signal). With External
Drive, the mainframe's pulse and trigger outputs are disabled.
In External Modulation Mode, an electrical signal supplied to the module's front panel (EXT MOD) by the
user will be converted into its optical analog. The quiescent optical level, corresponding to the zero point
that the input signal modulates about, is selected by the mainframe (External Modulation Level), but no
other parameters can be altered.
In the Impulse Mode, a narrow optical pulse of fixed width and amplitude is produced at the module
output (LIGHT OUT) with a corresponding pulse (of 5 ns duration) appearing at the mainframe (PULSE
OUT). As with the Pulse Mode, the trigger source may be internal, external or from manual (or remote
programming) control. Either a single delayed impulse or a pair of impulses separated by a delay may be
obtained. In Impulse Mode, External Drive operation is disabled; and Peak and Baseline Level settings
also have no effect.
CW Mode results in a steady-state optical output. The output power level in this Mode may
be adjusted by the mainframe (CW Level).
For more detailed information on the characteristics of each Mode and hour to control the module from
the mainframe, see the Specifications section and the 6040 manual.

OPERATING INFORMATION
General
POWER UP
When power is applied to the 6040 mainframe with a 106C, 155 or 130 module installed, the instrument
settings from the module's memory 0 are activated. The mainframe automatically checks what type of
plug-in module is in place and loads the appropriate parameters. The LCD, after showing the
mainframe's software version number and performing a memory check, will display "106C Ver. x.x" (or
“155 Ver. X.x” or "130 Ver. x.x") where "x.x" is the version number of the module.
Module Installation
The module must be installed with mainframe power off. A module can be damaged or have its
memory corrupted if inserted or removed from the mainframe with the power on. To install the module,
simply slide it in and tighten the mount screw knob.
Safety Precautions
Laser light emitted from the end of the connected light fiber is invisible. Fibers should be terminated in a
system which will not allow human exposure to this radiation. Do not stare into the beam or into a beam
from a reflecting surface. Use of controls or adjustments or performance procedures other than those
specified herein may result in hazardous exposure. Safety labels attached to the module are shown in
Figure 2-1.
Always keep the LIGHT OUT connector covered with the dust cap when a fiber is not attached in order to
avoid hazardous exposure and to keep the connector as clean as possible.
Warm Up Requirements
No warm up period, other than that necessary for the mainframe itself, is required.
TROUBLESHOOTING
Follow the procedure in the Troubleshooting section of the 6040 manual. Make sure that the module is
seated correctly in the mainframe. If the module's memory has been corrupted, a cold boot will put the
module's default settings (given below) into effect (as described in the Cold Boot paragraph in the 6040
manual).
11
OPERATING INFORMATION cont’d
The Quick Test procedure for the mainframe may be applied to the 106C/155/130 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. After Pulse Mode operation has been verified, the Impulse
Mode can be tested. This will require a sampling oscilloscope with a 1 GHz bandwidth. The impulse
should appear as a narrow pulse (approximately 400 ps). Its amplitude is roughly equal to that of a 0.3
mW, 5 ns pulse generated in the Pulse Mode. The CW and External Modulation Modes are similar.
These should produce continuous outputs. The output under External Modulation should follow any
waveform presented to the module's EXT MOD connector.

The following default settings for the 106C/153/130 module go into effect whenever a cold boot is
performed.

Front Panel Descriptions
LED INDICATORS
The 106C/155/130 module has two LED indicators on the front panel.
LASER ACTIVE will light when the instrument is in a state that can produce a light output.
LASER GUARD will light if the laser is being protected from an unsafe power output level, whenever the
Mode is changed and when the unit is first turned on. LASER GUARD will remain on if any unsafe circuit
conditions exist (e.g., excessive current driving the laser).

OPERATING INFORMATION cont’d
CONNECTORS
Three connectors appear on the 106C/155/130 module front panel.
LIGHT OUT provides the optical output from the module. A single-mode 8/123 Mm fiber with an ST
connector is required (the unit can be configured for other connectors; consult the factory for details). To
keep dust out of the connector when a fiber is not attached, a dust cap is provided.
EXT DR (External Drive) is a threaded SMA (3 mm) connector for accepting drive signal inputs to the
module.
EXT MOD (External Modulation) is a threaded SMA (3 mm) connector that accepts external signals to
modulate the instantaneous light output power level.
Rear Panel Description
The rear panel of the 106C/155/130 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.
The SMA (snap-on type) connector receives the high speed pulse generator DRIVE signal from the
mainframe. This signal is an ECL version of the mainframe's front panel PULSE OUT.
Mainframe Operation
This section presents information on how to operate the Model 6040 Universal Pulse Generator with the
Model 106C, 155 or Model 130 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.
Front Panel Programming
When operating the instrument from the front panel, certain control keys have module dependent action,
as indicated in the 6040 manual. The aspects of these keys, and the menus they control, that are not
general to the mainframe will be listed here.
An overall chart of the menu keys, showing which menu selections have control in each Mode, is given in
Table 2-1. An “x” in the column for a given Mode indicates that the menu selection operates in that Mode.

OPERATING INFORMATION cont’d
{MODE} The Mode menu for the 106C/155/130 has all four selections available: Pulse,
Impulse,
CW and External Modulation.
Pulse Mode can operate over the entire timing range of the 6040, producing flattopped delayed pulses. The Delay interval, Peak level. Baseline level and pulse
Width are all adjustable.
External Drive operation is available in this Mode, allowing the module to be
digitally modulated at rates from zero to 300 MHz (for nonzero Baseline levels) or
200 MHz (for zero Baseline level).
Impulse Mode produces pulses of fixed 400 ps width with fixed 30 u¥ baseline and
1 mW peak levels (typical).
CW Mode provides continuous wave optical output.
External Modulation Mode allows a user-provided analog or digital signal to be
linearly converted to its optical equivalent. Inputs ranging from 100 Hz to 700 MHz
are converted with 200 mV rms/mW sensitivity (typical).
{TRIG} The Trigger source and parameter menu, which operates in the Pulse and Impulse
Modes, has all five menu items: Single/Double Cycle, Internal Trigger (and Rate),
External Trigger (and Threshold), External Trigger Slope, and External Drive (and
Threshold).
Internal Trigger Rate and External Trigger Threshold are adjustable over the
6040's entire range.
External Drive is valid only in Pulse Mode (and has no effect in Impulse Mode).
The External Drive Threshold for the discriminator on the EXT DR input to the
module is adjustable from -2.3 V to +2.3 V with 10 mV resolution.
{TIMING} This module places no constraints on timing settings selected with the Timing
parameter menu.
15
OPERATING INFORMATION cont’d
{LEVEL} All four Level parameter menu selections are available for this module: Peak
Level, Baseline Level, External Modulation Level and CW Level.
Peak and Baseline Levels select the high and low power levels in Pulse Mode
operation. These levels may be set to zero or they may be adjusted between 30
µW and 1 mW in 3 MW steps (levels between zero and 50 µW may be selected
but output characteristics are not guaranteed). Peak Level and Baseline Level may
be set independently, but if Peak is set below Baseline the output will be a
constant CW at the Baseline Level.
External Modulation Level sets the quiescent optical power level. This may be
selected over the entire range of zero to 1 mW in 3 MW steps.
CW Level may also be adjusted to any power level between zero and 1 mW with 5
µW resolution.
{UNITS} This key is not used with the 106C/155/130 module (and has no effect).

SECTION 3
THEORY OF OPERATION
GENERAL
Module Interface
Figure 3-1 shows a simplified block diagram of the Module Interface board. The path for communication
between mainframe and module is via PS. The eight QAD lines and five QA lines are the bus interface
lines, and a MOD DIS line is used for disabling the Output board. Power is also delivered by P8.
The address demultiplexer and select logic circuitry decodes the bus signals and selects one of the other
blocks.
The I.D. ROM contains information necessary for operation specific to the Output board. This includes
boundaries for parameters, values used to initialize the nonvolatile RAM (NVRAM), and the version
number of the I.D. ROM.
The nonvolatile RAM is used for saving and retrieving ten panel settings. It also holds the GPIB/RS232
bus settings.
The digital control circuits are used to monitor and set the operating state of the Output board. The DACs
and amplifiers allow setting of up to four analog values used for level control. All of the control, status,
and analog signals are delivered to the Output board by two 20-pin connectors, J1 and J2.
Laser Driver Output
Figure 3-2 shows a simplified block diagram of the Laser Output board. The connection to the Module
Interface board is shown in the lower left hand corner. There are three analog lines used to set the output
levels and the threshold of the External Drive discriminator. The control lines select which Mode the
Laser Output will operate in.
The selection of the digital drive source is controlled by three digital control lines, EXT DRIVE ENABLE,
IMPULSE, and EXT MOD. These determine which of the two drive sources will be controlling the state of
S1, (a high speed transistor switch). A discriminator, whose threshold is set by the analog voltage EXT
DRIVE LEVEL, is connected to the drive source from the front panel EXT DR connector. The other signal
source is the rear panel DRIVE connector which delivers the mainframe's pulse generator output.
The level control circuitry sets one or both of the current sources as determined by the analog inputs
PEAK LEVEL, and BASELINE LEVEL and the Mode control lines. During the Impulse, CY and External
Modulation Modes, it uses the PIN detector in the laser module to monitor and stabilize the laser's
output. When LASER GUARD is active, the current sources are set for zero output.
17
THEORY OF OPERATION
The two current sources are used for different Modes. The current source on the left is used during Pulse
and Impulse Modes (to supply the Peak level), and during the External Modulation Mode. This current
source can be modulated from a wideband preamp which is driven by the front panel SMA connector
EXT MOD. The current is switched to the laser by SI, as determined by the DIGITAL DRIVE SELECT
and the drive signals. The current source on the right is used during PULSE MODE when a nonzero
Baseline level is selected and in the CW Mode.
The Laser Protection circuitry monitors the laser output and circuit conditions. If the laser output exceeds
a preset level, S2 will be closed and all laser drive current will be shunted to ground. The current is then
monitored until it is reduced below another preset value before S2 is allowed to reopen. This block drives
the front panel LEDs, LASER ACTIVE and LASER GUARD, which allow the user to monitor the state of
these circuits. The DAC EN signal is used to notify the Module Interface board of a potential problem and
disable its DACs, thus setting all level control voltages to zero. The MOD DIS signal is used to disable
the module's output.
The Laser Module is a single package that contains the laser diode, a PIN monitor diode, a
thermoelectric cooler (TEC), and a temperature sensing device. An 8/123 Um single-mode fiber is
connected to the front panel (LIGHT OUT). The TEC and thermistor are used in conjunction with an op
amp and transistor to regulate the temperature of the laser diode, thus improving power and wavelength
stability.
CIRCUIT DESCRIPTION
Module Interface Board (Schematic 6040-35)
The Module Interface board contains all the necessary circuits to allow the 6040 mainframe to control the
module. Interfacing between the module and the mainframe is realized via the 40-pin edge connector,
PS, This delivers eight data bits (QADO-QAD7) and 13 address bits (QADO-QAD7, multiplexed, and
QA8-QA12, nonmultiplexed). P8 also delivers power to the Interface board and the Output board.
Z2 is an eight bit latch that demultiplexes QADO-QAD7 to produce the lower eight address bits QAOQA7. This allows up to 8K bytes to be addressed within the Interface board, though not all of this is
utilized at the present time. Table 3-1 gives the memory map for the module.
Z1 is a dual quad selector. Z1 A is used to select between one of four 2K byte segments. These four
segments are used for: 1) Z3, the I.D. ROM; 2) Z4, the nonvolatile RAM; 3) reserved for expansion; 4)
Z5, Z6 and Z7, the digital and analog control of the output board. Z1B selects which IC in the fourth
segment is accessed.
Z3 is the I.D. ROM. It is an 8K byte ROM (only the lower 2K is used) that contains the module dependent
information necessary for the 60-40 to operate correctly.

THEORY OF OPERATION
This includes the Modes that are valid, parameter boundaries, and the type of output that the module has
(optical or electrical). It also contains the values for initializing the nonvolatile RAM.
Z4 is a 2K byte nonvolatile RAM (NVRAM). It is used to save instrument settings and power-on
conditions.
Z5 is a configurable Parallel Peripheral Interface 1C set up to allow 16 bits of output and eight bits of
input. The outputs are used to select the operating state of the Output board while the inputs monitor the
board's status.
DACs Z6 and Z7. in conjunction with op amps Z8 and Z9, generate analog signals that set the value of
the Peak, Baseline, and quiescent level of the output. They are also used to set the threshold level for
the External Drive discriminator. The variable resistors, R3-R6, are used to compensate for slight
differences in the DACs.
The voltage reference for the analog signals is CR1, a 6.2 V temperature compensated zener diode. Q1
is used to disable CR1 if the signal DAC EN is allowed to go up to +12 V. The Output board asserts this
in the event of a Mode change or if any unusual condition is detected.
The MOD DISABLE line allows the Output board to be disabled via the 6040 rear panel MODULE
DISABLE connector.
The Module Interface board has two grounds, digital and analog. The analog ground is used exclusively
by the DAC and op amp circuitry (Z6, Z7, Z8, Z9, etc.), while all other circuitry is connected to digital
ground. These are separated to prevent any noise or dc offsets by power supply return currents from
affecting the analog control voltages.
The 20-pin connectors J1 and J2 deliver the digital and analog control signals to the Output board, while
the 16-pin connector J11 delivers the power supply voltages. J3 is an expansion connector to be used in
conjunction with future modules.
LASER OUTPUT BOARD (Schematic 155-31)
Inputs and Control Signals (Schematic Sheets 1 and 2)
The Laser Output board receives three types of inputs: digital control signals from the Interface board via
P1, analog control signals from the Interface board via P2, and drive and external modulation inputs via
front or rear panel coax connectors. Four of the digital control signals, IMPULSE, EXT MOD, CW, and
BIAS, are used to control analog switches, Z14 and Z11 (sheet 1). These switches are in their low
impedance (closed) state when the control input, the terminal with inversion circle, is low (near ground).
20
THEORY OF OPERATION
Table 3-2 shows how these digital control signals affect the condition of the analog switches in each
Mode. The switches are identified by their control terminals (e.g., Z14-9); "L" and "H" indicate low and
high logic/voltage levels. By turning on and off these switches, these digital signals provide proper
routing for BASELINE LEVEL and PEAK LEVEL, the analog signals that control the amplitude at the
laser output. As an example, in the Pulse Mode with a nonzero Baseline (and not using External Drive),
the only high input to Z9 is BIAS (Z9-5). Thus Z9-10 and Z9-12 are both high and Z9-6 is low. Z14-1 is
low and this connects the BASELINE LEVEL amplitude control to Z8-3 via Z13-7 and Z14-3 Other Modes
may be similarly analyzed using this table.
Three digital control signals, EXT MOD, CW (sheet 1) and EXT DRIVE EN (sheet 2). select which drive
source is presented at the output of the ECL multiplexer, Z4 In Pulse Mode either the DRIVE signal from
the mainframe or the EXT DR signal from the module front panel can be selected. This signal, after
passing through Z3 and R162, becomes PREDRIVE, which determines when the laser is switched
between Peak and Baseline levels. In External Modulation Mode, EXT MOD selects X4 (Z4-11), which is
tied high, for the multiplexer output, causing PREDRIVE to be held high. In CW Mode, X2 is selected,
causing PREDRIVE to be held low.
Laser Module
The Laser Module is shown enclosed by dashed lines within which are six components. The laser itself is
the left hand diode whose anode is grounded and connected to the case at pins 13 and 13. The case is
connected to ground via pins 1 and 2. A 170 µH choke is provided internally for applying dc bias to the
laser. This is used in all the Pulse Modes with nonzero Baseline and in the CW Mode. The diode shown
between pins 7 and 8 is a built in monitor (detector) that is used for controlling the laser's output in the
CW, External Modulation, and Impulse Modes and is also used to detect excessive optical power. An
internal 22 ohm resistor provides wideband termination for the high speed signals from 06. A
thermoelectric cooler (TEC) is incorporated in the module and is shown connected between pins 3/4 and
3/6. Its associated temperature sensor is connected between pins 11 and 12. The temperature is
maintained at approximately 20° C by means of a feedback loop consisting of Z1 and 010. This loop
supplies enough cooling current to bring the sensor voltage to 2.9 V (Z1-3). R104 limits the maximum
current during start-up to a safe level (approximately 2 A).
CW Mode (Schematic Sheets 1 and 3)
CW operation utilizes the dc current source, Q1 and Z7. The voltage from Z8-1 (labeled CW OR
BASELINE LEVEL) is applied to one arm of the resistor bridge, R36, R37, R63 and R66. This same
voltage is forced to appear across R82 and R83 A typical calibration is for R82 and R83 to be 30 ohms
so that 20 mA/V is produced by Q1. This current flows (via R81, L1, and the internal 170 µH inductor)
through the laser to ground. Since PREDRIVE is held low the path for current through Q6 will be cut off.
Once the threshold current of the laser is exceeded, the relationship between the current in the laser and
its optical output is linear.
21
THEORY OF OPERATION
The path of the CW OR BASELINE LEVEL signal may be followed on schematic sheet 1. First, we note
that the PEAK LEVEL control voltage is inverted by Z13-1 and delivered to Z16-3 via R20. Second, we
determine the status of the switches that affect the CW OR BASELINE LEVEL signal. Z11-3, for
example, is connected to three such switches. From Table 3-1 it is seen that its control signal is
IMPULSE from Z9-2, and that it is high in the CW Mode. Thus, Z9-3 is not conducting. Z14-16 is similarly
found to be low so this switch is conducting. Also, Z14-1 is high which renders this switch open. Since
Z14-9 is low, the EXT MOD OR CW FEEDBACK signal from Z16-7 is applied to Z16-2. The output from
Z13-1 is also applied to Z16-3. The output from Z13-1 is not influenced by R22 because Z14-6 is open
and no voltage is applied to R22.

In summary, the PEAK LEVEL control voltage is inverted about ground by Z13-1 and also undergoes a
gain reduction of six (-6 V from PEAK LEVEL becomes +1 V at Z13-1). The current from the monitor
diode is converted at Z16-7 to approximately 1 V for a 1 mW optical output and is applied to Z16-2 where
it will almost cancel the signal from Z13-1. If this does not happen, a large error signal appears at Z16-1
where it passes via Z14-4 and Z8-1 to the current generator, Z7 and Q1 (sheet 3)
External Modulation Mode (Schematic Sheets 1 and 3)
We have traced in detail, for CW Mode, the manner in which the PEAK LEVEL control voltage causes a
predictable current to be applied to the laser. Similar considerations show how the quiescent light level
for the External Modulation Mode is derived. The PEAK LEVEL control voltage is still used to set the
desired optical level (around which the modulation will occur). Feedback via Z16-7 is used as with CW.
Z1 1-1 is high (as for CW) but now Z14-16 is also high. This has the effect of routing the error signal
(Z16-1) through Z8-7 (a precision rectifier).
It is then applied (sheet 3) as the ETT MOD OR PULSE AMPLITUDE signal to Z1-5 (a x2 attenuator
followed by an adjustable x3 gain stage). Since PREDRIVE is held high, the laser's dc bias is now
provided by Q9 (via 06) R108 samples the current which is compared to the voltage from Z1-7 by a
bridge arrangement (R72, R73, R74, R95). Z2-7 generates the error signal applied to Q8 and then to Q9.
The actual modulation is applied from J801, via FET current amplifier Q11, to Q8 where it generates a
base voltage for Q9 which (via R112) generates a predictable signal current through R108 and Q6 that
finally drives the laser. Although this circuit appears to be direct coupled from J801, it acts as if it were ac
coupled due to the action of Z2, which monitors the total laser current (flowing through R108). The low
frequency cut off is approximately 100 Hz.
23
THEORY OF OPERATION
Pulse Mode
In Pulse Mode, two conditions exist: the circuitry involved when the Baseline level is set to zero is
different from the circuits used with a nonzero Baseline. In Pulse Mode with zero Baseline, there is no
optical output between pulses (during a logical "zero" there is zero light output). The upper level is set by
the PEAK LEVEL control voltage which, in turn, determines the amount of current switched into the laser.
In Pulse Mode with a nonzero Baseline, both the upper ("one") and lover ("zero") logic levels must be
adjustable according to the Peak and Baseline settings.
Pulse Mode (Nonzero Baseline)
Pulse Mode with nonzero Baseline requires 1) producing a current that determines the optical power
radiated between pulses (the Baseline), and 2) calculating the difference between the desired Peak
power and the Baseline power, and then generating a pulse of corresponding amplitude. This pulse is
added to the already present Baseline level to produce the desired Peak level. The Baseline current is
generated and applied to the laser in the same manner as for CW operation, except that optical feedback
is not used.
The path from the BASELINE LEVEL control voltage is through Z13-7, Z14-3 (conducting), past Z14-14
and Z1 1-3 (both open), to Z8-1 (unity gain) and finally to Z7 (sheet 3). As stated above, Z7 and Q1 form
a current source, and this is what supplies the Baseline current to the laser.
The path from the PEAK LEVEL control voltage is through Z13-1 (sheet 1), Z16-1, past Z14-15 (open), to
ZS-7, through CR7, Z1-7 (sheet 3), and finally to Z2-7. As stated above, Z2-7, Q8 and Q9 form a current
source which also drives the laser. Pulse Mode differs from External Modulation in that the current is
switched by Q6 and Q7 (as defined by the level of the PREDRIVE signal) and there is no optical
feedback.
The pulse current (through Q6 and Q7) is determined for PEAK LEVEL by the precision rectifier formed
by ZS and CR7 and the two resistor dividers R31/R40 and R32/R39 (sheet 1). This circuit produces a
voltage which is the difference between the voltages at Z16-1 (the scaled version of the PEAK LEVEL
control voltage) and Z8-1 (the scaled version of the BASELINE LEVEL control voltage), yet not less than
zero. The output, at the cathode of CR7, is applied to Z1-5 (sheet 3) which provides an adjustable gain of
from xO.5 to x2. At this point, a 3 V difference between the control voltages has become 500 mV at Z1-7.
Z2-7 and R108 (47 ohm) convert this to approximately 10 mA, which is the value needed for a 0.30 mW
optical power change. Thus a 3 V difference between the PEAK LEVEL and BASELINE LEVEL control
voltages is converted to a 0.30 mW optical step. Since this step is added to the Baseline level already
present (via Z7, Q1) the Peak and Baseline levels are determined by their respective control voltages,
provided that the "gains" (voltage to current conversion factors) of the two channels are set to be equal.
24
THEORY OF OPERATION
PREDRIVE, the timing signal from the multiplexer (Z4), is applied (from Z3-2) to the base of predriver
Q4. Q4 and Q3 are a switching pair whose current is controlled by Z2-1 and Q3. The predrive current
through Q4 and 03 increases with increasing optical output and, as the current increases, the main
drivers Q6 and Q7 receive larger switching voltages. This is achieved by utilizing a current source.
comprised of Z2-1 and 03, which tracks the EXT MOD OR PULSE AMPLITUDE control voltage at Z1-7.
A small offset is introduced into this current source so that at very small pulse levels there is sufficient
predrive current to switch Q6 and Q7.
Pulse Mode (Zero Baseline)
With Zero Baseline, only the switching transistors Q6 and Q7 (sheet 3) supply current to the laser. The
PEAK LEVEL control voltage is processed directly through Z13-1. Z16-1 and Z8-7. Switches Z11-8, Z141, Z14-9 and Z14-6 are open and Z14-8 is closed. Thus Z13-1 is a x6 attenuator while Z16-1 is a x1
voltage follower. Since the switch Z14-1 is open, the BASELINE LEVEL control voltage is not presented
to Z8-3, which will now be held at ground by R24. This allows Z8-7 (through CR7) to be a xl follower of
the voltage at Z16-1
This has two implications. 1) the CW OR BASELINE LEVEL current source is turned off, which prevents
any quiescent light and 2) the PEAK LEVEL control voltage adjusts the pulsed current to values that
produce a power level between zero and 1.0 mW (the same range that the CW OR BASELINE LEVEL
current source uses with a nonzero Baseline Pulse Mode, as determined by the BASELINE LEVEL
control voltage.
External Drive (Schematic Sheet 2)
External Drive is used in the Pulse Mode to shift the source of the drive signal from the mainframe to the
front panel EXT DR connector. The circuits behave the same as under ordinary Pulse Mode operation
except that the PREDRIVE signal is now obtained (via the multiplexer Z4-5) from the External Drive
circuit. Two control signals from P2, EXT DRIVE LEVEL and EXT DRIVE POL, select the trigger
threshold and polarity for the signal presented to the EXT DR jack.
Impulse Mode
Impulse Mode is used to generate a narrow, fixed width and fixed amplitude pulse. The digital timing is
obtained from PREDRIVE (sheet 2). The leading edge of the impulse signal Z3-2 is caused by DRIVE
itself. R157 and Z3-15 provide a short time delay (less than 2 ns) that produces the trailing edge. The
result is a short, positive pulse delivered to the base of Q4 (sheet 3).
The predrivers (Q4 and Q3) and the main drivers (Q6 and Q7) have both been programmed by PEAK
LEVEL for a high (120% of full scale) current that represents the amplitude of the impulse waveform. In
order to assure fast response, the laser is biased to just above its threshold current by an auxiliary
feedback loop that holds the laser at this point regardless of duty factory variations. The optical output is
monitored by internal detector diode DSI-7, and in Impulse Mode represents the average optical power.
Both the Baseline level and the average power of the impulses themselves contribute to this signal. The
latter contribution varies with rep rate (duty factor).
25
THEORY OF OPERATION
Since it is desired to stabilize the Baseline level only, a signal proportional to the duty factor is required.
This signal is obtained from Z3-2 (via R163). Both signals are sent to the auxiliary feedback loop. The
IMPULSE COMPENSATION and IMPULSE FEEDBACK signals (sheet 1) are combined in Z6 along with
a dc level from R37 and are sent back (via Z11-3 and Z8-1) to the Baseline current source (Q1, sheet 2).
R37 adjusts for the small (approximately 10 µW) amount of residual light that is emitted between
impulses. R42 adjusts the balance between the optical sample (from D51-7) and the digital sample (Z3-
2) so that there is no change with varying rep rates.
Laser Protection (Schematic Sheets 1 and 3)
The laser is protected from excessive drive currents by a group of circuits referred to as LASER GUARD.
These circuits ensure that whenever an unusual situation occurs the laser is promptly shunted by a low
impedance. This action is called "crowbar." The path around the laser is from DS1-10 through LI, Q2,
and R79 to ground. Even if both sets of driver transistors (Q6, Q9 and Q1) were to short circuit, the
resulting current would be shunted around the laser by Q2.
If there is excessive current (20 mA or more) flowing in the crowbar transistor, Q2, it is sensed by Z7.
This causes a positive voltage (via CR14) to reinforce the triggering of Z12. The circuit remains in the
crowbar state until the over current condition is removed. Although the control circuits generally turn on
"gracefully" without excessive current transients, a time constant is provided (C59, R101) that turns Q2
on when the power is initially applied.
Another input to Z12-4 is from the internal monitor diode DSI-7. This produces a voltage across R102
and R103 that is set to trigger Z12 when the optical output becomes too high.
When a change of Mode is made, the ENABLE signal (Z9-9, sheet 1) triggers the crowbar action. This is
applied to a timer circuit, Z12, that acts to turn on the crowbar transistor Q2 (via 012) It also is triggered
at initial power-on by CR-23 and R130 A CROWBAR signal is sent to Z17-2 (sheet 1). This is another
timer that acts to further hold off the control circuitry and permit a smooth return to normal operation.
While Z17 is in its timing cycle, the LASER ACTIVE LED is turned off and a positive level from Z17-3 via
Z15-1 turns on the LASER GUARD indicator. After several seconds the Z17 timer will recover (if no over
current condition is present) and allow the control circuits to recover.

MAINTAINENCE
Light Output Connector
For satisfactory performance, proper care in the use of the optical components is necessary. There must
be no contamination to interfere with the passage of light through the fiber end connections and the
