Section 1: Introducing the Model 9500B 1-3
Final Width = 215mm
Descriptions assume 9500B/1100
In order to be able to calibrate a wide range of different oscilloscope
parameters, flexibility is built into the design of the 9500B. Of the five
major modes only two: 'Manual' and 'Procedure', determine the everyday
front-panel use of the instrument. The other three are concerned with
system configuration, 9500B calibration and 9500B selftest.
1.2.2.1 Manual Mode
In 'Manual' Mode: the 9500B is operated entirely from the front panel.
The operator is in complete charge of the calibration procedure, usually
interpreted locally from the UUT oscilloscope manufacturer's calibration
data. Refer to Sections 3 and 4.
1.2.2.2 Procedure Mode
'Procedure' Mode involves the use of a memorized calibration procedure.
The manufacturer's data for the UUT oscilloscope will have been
interpreted into a series of calibration operations, which are programmed
on to a memory card. When the card is inserted into the 'PROCEDURE'
slot in the front panel, the 9500B will move from operation to operation,
switching the 9500B controls automatically, and issuing a series of
requests for the operator to change UUT switching and connections.
Refer to Section 5.
Portocal II v 1.7 (see paras 1.3) can be used to generate calibration
sequences on procedure cards to calibrate UUT oscilloscopes using the
Model 9500B.
1.2.2.3 Configuration Mode
This mode, requiring a password, provides access for the user-selectable
configuration options. These include:
• Set the internal reference frequency.
• Adjust the threshold for high voltage warning.
• Change the IEEE-488 bus addresses.
• Select or deselect remote emulation (SG5030 or CG5010/5011).
• Enable or disable use of an external printer (Procedure mode only).
• Set the instrument to power-up in either Manual or Procedure mode.
• Alter the passwords required for entry to Configuration and
Calibration modes.
• Select the frequency for External Reference Input.
• Set the frequency of, or disable, External Reference Output.
• Alter the memorized date and time, and its format of presentation.
• Set User language (for Procedure mode only).
• Determine the percentage of UUT measurement tolerance beyond
which a 'Borderline' result is called (in Procedure mode only).
• Enable or disable the use of a data card for 'RESULTS' (Procedure
mode only).
• Enable or disable fields in certificates to accommodate Engineer's
note (Procedure mode only).
• Select the type of certificate required to be printed, alter some of the
certificate details, and re-format its pages (Procedure mode only).
• Clear the displayed list of Procedure mode users.
1.2.2.4 Calibration Mode
Calibration of the 9500B itself cannot proceed until two security
measures have been satisfied:
1. The rear panel 'CAL' switch must be set to its 'ENABLE' position.
Note: The switch is recessed behind a small hole — at shipment this
hole is covered by a paper seal which should not be broken
except for an authorized recalibration.
A broken seal is regarded as invalidating the previous
calibration.
2. An acceptable password must be entered on the screen.
Once into Calibration mode, there are three types of calibration available.
These should be used only under supervision — if it is suspected that
calibration may be required, contact your Fluke Service Center.
•'Special' calibration, enabling automatic calibration of the main
A-D converter.
•'Factory use only' is an initial calibration which is not available to
users, requiring a second password.
•'Standard Calibration' will initiate manual calibration procedures
for those functions requiring recalibration.
Calibration of the 9500B is detailed in Section 9: 'Specification
Verification' and Section 10: 'Calibration' (Adjustment). Those 9500B
calibration sequences which are user-accessible are detailed in Section
10. If it is suspected that some other calibration may be required,
contact your Fluke Service Center.
