2Overview
DESCRIPTION
The DA18000 Differential Amplifier is a very high bandwidth differential amplifier with 50 Ω
inputs and high common mode rejection, and is designed to be used exclusively with the
SDA 18000 Serial Data Analyzer.
The amplifier contains common circuitry such as power supply, communication and control
and AutoColor ID. The DA18000 amplifier utilizes digital filtering to improve the system fre-
quency response. The response is corrected through the use of digital filters which are spe-
cifically tailored through calibration to optimize the frequency flatness of the amplifier. This
provides the highest fidelity in eye pattern measurements.
Certificate of Calibration is supplied with each amplifier indicating that the system will meet
the specifications with those components listed in the Certificate.
ESD Sensitive: The inputs of the DA18000 amplifier are sensitive to
Electrostatic Discharge (ESD). To avoid causing damage to the ampli-
fier, always follow anti-static procedures (wear wrist strap, etc.) when
using or handling the 2.92 mm connectors.
APPLICATIONS
The DA18000 amplifier is ideally suited for acquiring differential signals common in high
speed serial data applications with fine pitch ICs and high lead count where high speed,
minimal loading and accurate jitter measurement are required.

4Operation
HANDLING THE AMPLIFIER
The DA18000 Differential Amplifier is a precision test instrument; exercise care when han-
dling and storing the amplifier. Always handle the amplifier by the body. Avoid putting exces-
sive strain on the attached cables or exposing the cables to sharp bends.
ESD Sensitive: The inputs of the DA18000 amplifier are sensitive to
Electrostatic Discharge (ESD). To avoid causing damage to the ampli-
fier, always follow anti-static procedures (wear wrist strap, etc.) when
connecting cables to the input.
2.92 MM CONNECTORS
The 2.92 mm connector of the DA18000 amplifier is a precision coaxial connector that oper-
ates up to 40 GHz. It is compatible with SMA, WSMA and 3.5 mm connectors.
To avoid misalignment of the male pin to the female contact, the male pin of the 2.92 mm
connector is made shorter than the SMA or 3.5 mm connector pins. This way the outer hous-
ing is properly aligned prior to mating of the center conductors. Because of the new design,
the insertion force has been reduced from about 27 N in SMA and 3.5 mm connectors to
about 2.3 N with the 2.92 mm design. 2.92 mm connectors can be tightened to the same
torque specification as is used for type SMA, without damage.
Note
When connecting SMA or 3.5 mm connectors, always align the male and female
parts before insertion to prevent damage to the female center connector.
2.92 mm connectors use air for the dielectric, as opposed to PTFE resin in type SMA. For-
eign material such as excessive dust can enter the dielectric pocket and degrade the high
frequency performance. Should this occur, remove the foreign material, using a jet of com-
pressed air or gas. Disposable cans of compressed gas for dusting purposes are readily
available from photo or electronic equipment suppliers.
Never insert an object into the connector in attempting to clean it. The
center contact can be easily bent out of position, destroying the
connector.
COMPATIBILITY
The DA18000 Differential Amplifier is designed to be used exclusively with the SDA 18000
Serial data Analyzer. However it includes frequency compensation data compatible with
lower BW WaveMaster, SDA, and DDA 5005 oscilloscopes.
CONNECTING THE AMPLIFIER TO A LECROY SERIAL DATA
ANALYZER
The DA18000 amplifier has been designed for exclusive use with the SDA 18000 Serial
Data Analyzer.
For optimum performance and full bandwidth always connect the amplifier only to channel 1
of the SDA 18000 analyzer.
CAUTION

DA18000 Differential Amplifier
4-2 DA18000-OM-E Rev A
To attach the amplifier to the LeCroy oscilloscope, align the interface connector with the
input connector and push the interface toward the oscilloscope.
A click will be heard when the amplifier’s interface latches to the oscilloscope. This amplifier
also uses the thumb screws to secure the interface to the oscilloscope.
Thumb screws should be tightened finger tight only. Use of pliers or
another tool may overtighten the screws, resulting in damage to the
oscilloscope.
To remove the DA18000 from the LeCroy oscilloscope, move the amplifier up and down
while pulling gently till a loud snap is heard indicating that the amplifier is unlatched from the
oscilloscope.
AUTOCOLOR ID
When the amplifier is connected to a SDA 18000, the LED will illuminate in the default color
of the channel to which the amplifier is connected.
OPERATION WITH THE SDA 18000
Figure 4-1. Vertical Menu
When the amplifier’s output connector is attached to the SDA 18000 oscilloscope’s input
connector, the oscilloscope will recognize the amplifier and activate the vertical channel
functions in the user interface. Figure 4-4. Refer to your oscilloscope’s instruction manual for
operations of the oscilloscope.
CAUTION

Operation
DA18000-OM-E Rev A 4-3
Control through the oscilloscope’s interface can be found in the screen menu of the channel
to which the amplifier is connected.
Touching the tab indicating the attached amplifier (in this case DA18000) will activate the
amplifier menu screen. Figure 4-5.
The amplifier information frame shows the characteristics of the amplifier only.
In some applications it may be desirable to turn the amplifier’s AutoColor ID OFF or ON with
touching the Led On frame.

CONNECTING THE AMPLIFIER TO THE TEST CIRCUIT
For all modules and interconnect leads, positive voltages applied to the + input relative to
the – input will deflect the oscilloscope trace towards the top of the screen.
2.92 mm Input Cables
The 2.92 mm Interconnect System has been designed to connect directly to female 2.92 mm
connectors as well as to the higher performance 3.5 mm and 2.92 mm female connectors.
The Interconnect Cable connects to the amplifier and the matched pair of SMA Cable con-
nect to the Interconnect Lead.
The connector should be tightnened to a torque of 0.06 Nm (8 in.-oz.).
Note
The 2.92 mm Input Cables are supplied as a matched pair. Individual cables should
not be interchanged between amplifiers.

USE OF DC ÷2 ATTENUATOR
The ÷2 attenuator should be used when the common mode or differential voltage of the cir-
cuit under test is unknown or exceeds the maximum voltage specified. (See section 9, Spec-
ifications). The use of the attenuator will also reduce the reflections, thus improving the
VSWR.
The DA18000 amplifier has no method to detect the presence or absence of the attenuator.
To maintain correct vertical scale factor and amplitude measurement results, you must
inform the oscilloscope when the attenuator is being used. This is done in the Vertical
Adjust →DA18000 control dialog for the channel that the amplifier is connected to.
DYNAMIC RANGE
The DA18000 amplifier has no gain or attenuation control. The system gain is fixed at x1.
Exceeding the common mode range may introduce distortion to the output signal. Use of the
÷2 attenuators will increase the differential mode range; however, due to power limitations,
they will not increase the common mode range.
There are two common mode voltages:
±10 V without a ÷2 attenuator
7 Vrms with a ÷2 attenuator

DIFFERENTIAL MODE AND COMMON MODE
Differential amplifiers sense the voltage difference which appears between the + input and –
input. This voltage is referred to as the Differential Mode or Normal Mode voltage. The volt-
age component which is referenced to earth and is identical on both inputs is rejected by the
amplifier. This voltage is referred to as the Common Mode voltage and can be expressed as:
DIFFERENTIAL MODE RANGE AND COMMON MODE RANGE
Differential Mode range is the maximum signal which can be applied between the + and -
inputs without overloading the amplifier/amplifier, which otherwise would result in clipping or
distorting of the waveform measured by the oscilloscope.
The Common Mode Range is the maximum voltage with respect to earth ground which can
be applied to either input. Exceeding the common mode range can result in unpredictable
measurements. Because the Common Mode signal is normally rejected and not displayed
on the oscilloscope, the user needs to be careful to avoid accidentally exceeding the com-
mon mode range.
Because the input signal of a differential amplifier is not referenced to ground, the concept of
"Vpeak" versus “Vpeak-peak” may be confusing.
With a ground referenced signal, Vpeak is the maximum instantaneous voltage amplitude the
signal will have with respect to ground. In a differential system, there is no ground reference.
Therefore the Differential Mode Range refers to the maximum instantaneous amplitude of
the signal difference between the positive input and the negative input. Since most amplifi-
ers have symmetrical bipolar inputs, the value is generally expressed as an absolute value,
and can have either polarity.
For example, an amplifier with a differential mode rating of ±1 V can have a maximum volt-
age difference appearing at any instant in time of 1 V between the inputs. The polarity could
be either positive or negative. This does not imply that the number can be doubled to 2 volts,
however. For clarity, consider the following table of absolute voltages applied to the inputs of
a differential amplifier that has a differential mode range or ±1 V and a common mode range
of ±5 V:
VCM
V+input V–input +
2
--------------------------------------
=

DA18000 Differential Amplifier
6-2 DA18000-OM-E Rev A
Some amplitudes are specified as "peak to peak." The differential amplifier peak-to-peak
range will be twice the peak differential mode range specification as, at any instant in time,
the maximum voltage amplitude signal would be one-half of the peak-to-peak value.
In a balanced differential system, the signal on each output will be an inverted copy of the
other input. For example, an LVDS system may have a pair of outputs, each of which has a
voltage swing of 0 to +370 mV. A logic 1 would be represented when the + output is at
+370 mV, while the - output is at 0 V. A logic zero would be the opposite polarity: the + output
at 0 V and the - output at +370 mV. Note that even though both outputs swing 370 mV, the
maximum difference voltage between them at any instant is still within ±370 mV. So this sig-
nal could be measured with a differential amplifier that has a differential mode range of ±400
mV.
COMMON MODE REJECTION RATIO
The ideal differential amplifier/amplifier would sense and amplify only the differential mode
voltage component and reject all of the common mode voltage component. Real differential
amplifiers are not perfect and a small portion of the common mode voltage component
appears at the output. Common Mode Rejection Ratio (CMRR) is the measure of how much
the amplifier rejects the common mode voltage component. CMRR is equal to the differential
mode gain (or normal gain) divided by the common mode gain. Common mode gain is equal
to the output voltage divided by the input voltage when both inputs are driven by only the
common mode signal. CMRR can be expressed as a ratio (e.g. 10,000:1) or implicitly in dB
(e.g. 80 dB). Higher numbers indicate greater rejection (better performance).
The first order term which determines the CMRR is the relative gain matching between the +
and – input paths. To obtain high CMRR values, the input attenuators in a differential ampli-
fier are precisely matched to each other. The matching includes the DC attenuation as well
as the capacitance which determines the AC attenuation. As the frequency of the common
