IF THIS PRODUCT IS NOT USED
AS SPECIFIED, THE PROTECTION
PROVIDED BY THE EQUIPMENT
COULD BE IMPAIRED. THIS
PRODUCT MUST BE USED IN A
NORMAL CONDITION (IN WHICH
ALL MEANS FOR PROTECTION
ARE INTACT) ONLY.
The types of product users are:
–
–
–
–
Responsible body is the individual or
group responsible for the use and
maintenance of equipment, for
ensuring that the equipment is
operated within its specifications and
operating limits, and for ensuring that
operators are adequately trained.
Operators use the product for its
intended function. They must be
trained in electrical safety procedures
and proper use of the instrument.
They must be protected from electric
shock and contact with hazardous
live circuits.
Maintenance personnel perform
routine procedures on the product to
keep it operating properly (for
example, setting the line voltage or
replacing consumable materials).
Maintenance procedures are
described in the user documentation.
The procedures explicitly state if the
operator may perform them.
Otherwise, they should be performed
only by service personnel.
Service personnel are trained to work
on live circuits, perform safe
installations, and repair products.
Only properly trained service
personnel may perform installation
and service procedures.
Exercise extreme caution when a shock
hazard is present. Lethal voltage may be
present on cable connector jacks or test
fixtures. The American National Standards
Institute (ANSI) states that a shock hazard
exists when voltage levels greater than
30 V RMS, 42.4 V peak, or 60 VDC are
present.
Keysight M9217A Service Guide
A good safety practice is to expect that
hazardous voltage is present in any
unknown circuit before measuring.
Operators of this product must be
protected from electric shock at all times.
The responsible body must ensure that
operators are prevented access and/or
insulated from every connection point. In
some cases, connections must be
exposed to potential human contact.
Product operators in these circumstances
must be trained to protect themselves
from the risk of electric shock.
Before operating an instrument, ensure
that the line cord is connected to a
properly-grounded power receptacle.
Inspect the connecting cables, test leads,
and jumpers for possible wear, cracks, or
breaks before each use.
When installing equipment where access
to the main power cord is restricted, such
as rack mounting, a separate main input
power disconnect device must be
provided in closed proximity to the
equipment and within easy reach of the
operator.
For maximum safety, do not touch the
product, test cables, or any other
instruments while power is applied to the
circuit under test. ALWAYS remove power
from the entire test system and discharge
any capacitors before: connecting or
disconnecting cables or jumpers,
installing or removing switching cards, or
making internal changes, such as
installing or removing jumpers.
Do not touch any object that could
provide a current path to the common

Performance Verifications and Adjustments
Module Calibration Procedure
The calibration process includes the following steps:
1
Verification — Verify the existing operation of the instrument. This step confirms
whether the instrument is operating within its specified range.
2
Adjustment — Perform an external adjustment of the instrument that adjusts the
calibration (Offset/Gain) constants.
3
Re-verification — Repeat the verification procedure to ensure that the instrument is
operating within its specifications after adjustment.
These steps are described in more detail in the following sections.
Calibration interval
The accuracy requirements of your application determine how often the M9217A should be
calibrated. Keysight recommends that a complete calibration should be performed at least
once every year. This interval can be shortened based on the accuracy demands of your
application.
Test conditions
Follow these guidelines to optimize the connections and the environment during
calibration:
NOTE
–
Always connect the outputs of the M9217A to the external equipment with short
cables. Long cables and wires act as antennas, picking up extra noise that can affect
measurements.
–
Keep relative humidity between 10% and 90% non-condensing, or consult the M9217A
specifications for the optimum relative humidity.
–
Maintain an ambient temperature of 23 ±5 °C.
–
Allow a warm-up time of at least 60 minutes after enabling the instrument. To enable
the instrument use the driver commands KtM9217_Open. Allow a warm-up time for
the used external equipment according to manufacturers guidelines.
The warm-up time ensures that the instruments circuitry is at a stable operating
temperature.
–
34
During calibration, connect the calibrator LO source to earth ground at the calibrator. It
is important that the LO to earth ground connection be made at only one place in the
circuit to avoid ground loops.

Performance Verifications and Adjustments
Performance Verification Tests
These performance verification tests verify the digitizer is operating within the
specifications.
Create your own performance test program using the fundamental C function calls
provided by the instrument driver. To use these functions, include
KtM9217Fundamental.h in your code when writing your test procedure.
DC voltage accuracy
This procedure verifies the DC accuracy specifications of the digitizer. It can be used to
determine if the digitizer meets its published specifications for DC accuracy or if it is in
need of adjustment. It can also be used to verify if the adjustment procedure was
successful in adjusting the digitizer accuracy to meet its published specifications.
The DC accuracy verification procedure uses a calibration standard of known accuracy to
generate DC voltage input signals that are measured by the digitizer. You are required to
calculate the average value from the measured data samples. The average measurement
results are then compared to the known values of the inputs to determine the measurement
error of the digitizer. Large data records are acquired and averaged in order to reduce the
effects of noise on the measurements and to more accurately determine the DC value of
the input signals.

verification of the zero can be obtained by connecting a 50 Ω termination to the input
connectors.
Shock Hazard. This procedure requires the application of up to 240 Vdc. Ensure all test
connections are properly insulated and shielded.
AC flatness functional test (optional)
This procedure verifies the AC flatness characteristics of the digitizer. AC Flatness is an
optional test because it is a typical characteristic that is not warranted. The AC Flatness
was adjusted when the module was manufactured and is normally not adjusted again. The
AC flatness is relative to the response at 20 kHz.
The AC flatness test procedure consists of measuring both 20 kHz and 4 MHz input signals
on selected ranges and comparing their relative values. The test signals are generated by
an Arbitrary Waveform Generator (AWG). The input signals are measured by the digitizer.
You are required to calculate the root mean square (RMS) value from the measured data
samples. The measured signal amplitudes of the two frequency points are then compared
to each other.

Performance Verifications and Adjustments
Flatness
This procedure adjusts the AC Flatness characteristic of the digitizer. Two adjustments on
each channel can be made. One adjustment is done on the 16 V range and the second one
is done on the 64 V range.
Adjustments only need to be done if the AC Flatness (optional test) in the service guide
exceeds its limits. The 16 V adjustment needs to be done before the 64 V adjustment,
because adjustments to the 16 V will also directly affect the 64 V adjustment. Thus if the 16
V adjustment is done, then the 64 V adjustment must also be done. If only the 64 V
adjustment is needed, then not adjusting the 16 V is fine.
The 16 V AC flatness adjustment procedure consists of measuring a reference Vrms_ref,
20 kHz Sinewave on the 16 V range, and then changing the frequency to 4 MHz in order to
measure Vrms_4MHz .
With the measurements, calculate the flatness using the following formula:
Vrms 4MHz
Flatness = 20 log ⎛ ---------------------⎞
⎝ Vrms 20kHz⎠
The 4 MHz measurement and flatness calculation is performed repeatedly while adjusting
the capacitive trimmer pot for ATT2. Tuning is performed until the flatness is
+0.10 dB ±0.05.
The 64 V AC flatness adjustment procedure is similar to the 16 V AC flatness adjustment.
You are to adjust the capacitive trimmer pot for ATT1. The tuning is performed until the
flatness is +0.45 dB ±0.125.

Troubleshooting Techniques
There are two main steps to troubleshoot a faulty M9217A module:
1
Identify the problem, and
2
Test the module assembly to isolate the cause.
Identifying the problem
Module problems can be divided into three general categories:
–
Operator errors
–
Catastrophic failures
–
Performance out of specification
Operator Errors
Apparent failures may result from operator errors.
Catastrophic Failure
If a catastrophic failure occurs, use the M9217A Soft Front Panel (SFP) to communicate
with the module in order to troubleshoot and isolate the module problem.
Performance Out of Specification
If the module performance is out of specification limits, use the adjustment/calibration
procedures in Chapter 3 to correct the problem.

Repair/Maintenance Guidelines
This section provides guidelines to repair and maintain the M9217A module, including:
–
ESD precautions
–
Soldering printed circuit boards
–
Post-repair safety checks
ESD precautions
Electrostatic discharge (ESD) may damage MOS, CMOS, and other static sensitive devices
in the M9217A module. This damage can range from slight parameter degradations to
catastrophic failures.
When handling module assemblies, follow these guidelines to avoid damaging module
components:
–
Always use a static-free work station with a pad of conductive rubber or similar material
when handling module components.
–
After you remove the module from the mainframe, place the module on a conductive
surface to guard against ESD damage.
–
After you remove a MOS or CMOS device from an assembly, place the device onto a
pad of conductive foam or other suitable holding material.
–
If a device requires soldering, be sure that the assembly is placed on a pad of
conductive material. Also, be sure you, the pad, and the soldering iron tip are grounded
to the assembly. Apply as little heat as possible when soldering.
–
When you replace a MOS or CMOS device, ground the foam before removing the device
from the foam.
When soldering to any circuit board, keep in mind the following guidelines:
–
Avoid unnecessary component unsoldering and soldering. Excessive replacement can
result in damage to the circuit board and/or adjacent components.
–
Do not use a high power soldering iron on etched circuit boards as excessive heat may
lift a conductor or damage the board.
–
Use a suction device or wooden toothpick to remove solder from component mounting
holes. When using a suction device, be sure the equipment is properly grounded to
prevent electrostatic discharge from damaging CMOS devices.

Post-repair safety checks
After making repairs to the M9217A module, inspect the module for any signs of abnormal
internally generated heat, such as discolored printed circuit boards or components,
damaged insulation, or evidence of arcing. Determine and correct the cause of the
condition. Then run the Verification Tests to verify that the module is functional.

Keysight Technologies Calibration Services
When your module is due for calibration, contact your local Keysight Service Center for a
low-cost recalibration. The M9217A is supported on automated calibration systems, which
allows Keysight to provide this service at a competitive price.
Calibration interval
A one-year interval is adequate for most applications. Accuracy specifications are under
warranty only if adjustments are made at regular calibration intervals. Accuracy
specifications will not be offered warranty beyond the one-year calibration interval.
Keysight does not recommend extending calibration intervals beyond two years for any
application. Keysight recommends that a complete readjustment should always be
performed at the calibration interval. This will ensure that the M9217A will remain within
specifications for the next calibration interval. The re-adjustment provides the best longterm stability and accuracy.
