The Agilent Technologies B Series of miniature probes significantly reduces the problem of probing densely populated integrated circuit components and characteristically small conductors on printed circuit boards. These small, lightweight probes allow measurements that were previously very difficult, while reducing the hazard of shorting. The probe body fits in the hand as comfortably as a pencil.

Each probe includes a browser tip that will not slip off of the test point being probed and short to some adjacent point. The browser uses a crown point that “digs in” to solder, and will not slip.

These probes include a variety of ground leads for attaching to many different ground points. Probe packaging provides convenient storage and ordering information for replacement parts.

Other key features

• Narrow, sharp, replaceable probe tip.

• Browser attachment with ultra-sharp crown point. Use this to probe the circui t in de bug mode. The crow n point will not easi ly slip off of the lead you are probing. The pogo pin allows hand movement without losing contact.

• An assortment of long and short ground leads for connecting to a wide variety of points.

• Handle unscrews and pulls back to reduce the size of the probe.

• General-purpose retractable hook tip made of strong, durable music wire.

• Flexible, light-weight cable with kevlar strengthener.

• Multi-position barrel insulator exposes as much or as little probe ground as desired at the probe tip.

• P robe comes in a con veni e nt sto rage box, wi th lab eled infor matio n on how to reorder parts.

• Automatic Probe Identification Pin (Agilent 10441B only).

Bandwidth considerations

The dominant probe limitation to system bandwidth is its input capacitance, assuming that the high-frequency compensation adjustments have been made. The displayed bandwidth of any measurement system using an oscilloscope and probe is determined by four factors: probe input capacitance, source impedance, source bandwidth, and oscilloscope bandwidth.

Safety considerations

WARNING SHOCK HAZARD!

These probes are designed for use with oscilloscopes that have a common terminal at GROUND POTENTIAL (in accordance with OSHA requirements and the National Electric Code). Exposed metallic surfaces of the probe and the oscilloscope MUST BE GROUNDED. Failure to ground the common terminal during certain applications, such as those requiring the oscilloscope to be powered from an external battery, might expose the operator to an electrical shock hazard that could be lethal (depending on voltage and current conditions.)

Cleaning the probe

If the Agilent 10400B Series Probe requires cleaning, disconnect it from all power sources and clean it with a soft cloth dampened with a mild soap and water so l u tio n . Ma k e s ure th e pro b e is c o mp let e l y dr y be fo re r e con n ec ti ng i t t o a pow e r source.

Agilent 10400B Series Miniature Passive Oscilloscope Probes

To connect oscilloscope probes

1 Attach the probe connector to the desired oscilloscope channel. 2 Connect the probe to the circuit using any of the probing aids.

Page 13

Agilent 10400B Series Miniature Passive Oscilloscope Probes

To operate the probe

When operating the Agilent 10400B Series Probes, these additional parts can help:

• SMD Clip

The SMD clip lets you connect the Agilent 10400B Series Probe to SMT parts with dual lead adapter. See “Available accessories” described earlier for more information.

•BNC-to-Probe Tip Adapter

This tip adapter lets you attach the probe to a BNC cable.

• Spring Ground

The spring ground attaches to the probe to make ground contact with the circuit board, while letting you angle and maneuver the probe around an area.

CAUTION Do not solder probe tip to any surface. Solder will damage the probe tip.

CAUTION If you are using the probe without any accessories, the probe could cause a

short if you drop it within the circuit.

1 Attach the probe to the circuit.

You may use the probe tip pin without any accessories for probing in places that are difficult to reach.

You may unscrew the cable strain relief from the probe and slide it back on the cable when using two or more probes in cl ose proximity. When using the probe without the browser or retractable hook tip, you should use the barrel insulator (a supplied accessory) to cover the tip ground shield to prevent the hazard of shorting when you are probing the circuit. You may unscrew the barrel insulator and remove it to accommodate tight probing situations.

Page 14

Agilent 10400B Series Miniature Passive Oscilloscope Probes

To operate the probe

The barrel insulator can be screwed to multiple positions:

• With the barrel insulator screwed all the way on, you may add a spring ground (a supplied accessory) to the probe tip to provide ground contact.

With the barrel insulator screwed most of the way out, the barrel insulator covers the ground shield by the probe tip. Ground the probe tip and barrel insulator.

Ground the probe by attaching either the alligator ground, socket ground, or spring ground. Any of these ground accessories provides reference for a ground point.

To avoid possible shorting of other circuitry, use the barrel insulator in conjunction with any of the grounding accessories. For optimum performance, use the shortest ground lead.

The browser.

The browser tip has a crown point that digs into solder and will not slip. The spring-loaded pogo pin allows hand movement without losing contact.

4 The retractable hook tip.

Attach the hook tip to a probing point by pressing the retractable hook tip body towards the probe body. Place the hook tip around the probing point, then release the retractable hook tip body.

The retractable hook tip is used for most typical in-circuit probing and ICs.

The Agilent Wedge Probe Adapter

The Agilent Wedge Probe Adapter makes contact with legs of the IC under test when the Agilent Wedge Probe Adapter conductors are inserted into the space between the legs of the IC. If you are using the Agilent Wedge Adapter, refer to the supplied Agilent Wedge Adapter User’s Guide.

Agilent 10400B Series Miniature Passive Oscilloscope Probes

Compensation adjustments

You can adjust the probes for both low-frequency compensation and highfrequency compensation. Low-frequency compensation is an operating adjustment. You should perform high-frequency compensation periodically according to maintenance schedules.

When to Adjust Probe Compensation

Low-frequency compensation is adjusted when the probe is first connected to the oscilloscope. Probe compensation will usually hold over all the attenuator ranges when used with a Agilent Technologies oscilloscope. If the input capacitance of the oscilloscope changes as ranges are switched, compensation must be adjusted each time a new range is selected.

Adjusting low-frequency compensation

Before you can have a flat frequency response when using a compensated passive divider probe, you must compensate the probe’s cable capacitance and scope input capacitance to optimize the step response for flatness. You should compensate your probe to match its characteristics to the oscilloscope. A poorly compensated probe can introduce measurement errors.

Connect the probe from the appropriate oscilloscope channel to the

front-panel probe adjust signal terminal [ ] on the scope.

You can attach the probe with the hole in the probe body facing up to allow adjustment.

Press Autoscale.

frequency compensation adjustment on the probe for the flattest pulse possible as shown below.
