Reliable Connections Ensure Accuracy

• Impedance

High input impedance ensures minimum intrusion on your circuit. Although many probes might be acceptable for lower frequencies, capacitive loading becomes significant at higher frequencies. The Agilent probing products perform over a wide frequency spectrum.

• Ruggedness

Probes with quality mechanical design provide solid electrical connections. Intermittent open circuits would only add one more variable to your debugging equation. Agilent probes are mechanically designed to relieve strain and ensure rugged, reliable connection.

• Immunity to Noise

Electromagnetic noise can corrupt data captured by the logic analyzer. Agilent probing solutions are designed for a high immunity to transient noise.

• Performance

Agilent logic analyzers have front-end circuitry that supports the state and timing specifications of the analyzer. This circuitry, together with the Agilent probing solutions described in this document, will accurately capture the target signals at the specified clock rates.

Other Considerations

Physical connection compatibility between various Agilent probes may allow you to mix and match a variety of probes and accessories. However, a probe accessory designed for slower clock speeds will not deliver high-speed target performance simply because it is used with a higher speed analyzer module. Also, the serial connection of multiple probe leads and/or accessories will degrade signal integrity.

Signal Frequency Content Drives Probing Solutions

Faster clock rates demand tighter timing tolerances, such as setup and hold specifications. Systems with faster clock rates usually have shorter rise and fall times. Signals with shorter transition times have more high frequency content and are more susceptible to high frequency analog problems such as cross talk, reflections, ground bounce, noise and emissions. Susceptibility of a system to analog problems relates to the transition times of the signals, not the clock rate. A system with slow transition times cannot have high clock rates. However, it is possible for a system with slower clock rates to have signals with very fast transition times.

General-purpose probing solutions provide the analog bandwidth required to run each logic analyzer module at its maximum clock rate. The high input impedance of these probes, especially at high frequencies, presents a minimal load to most systems. Systems that are operating with little margin should be designed with consideration for both the system components and the input impedance of the probing solution being used during debug. Input impedance specifications or equivalent load diagrams can be found for each of the probing solutions described in this document.

Which Logic Analyzer?

Agilent logic analyzers have two methods of connection to the probes. One uses a 3M-style connector with two rows of 20 pins on 0.1-inch centers, as illustrated in Figure 1.1. Probes for these analyzers are identified in this document as “for analyzers with 40-pin pod connectors.”

The other style uses a 90-pin, high-density connector, as illustrated in Figure 1.2. Probes for these analyzers are identified in this document as “for analyzers with 90-pin pod connectors.”

Currently available Agilent logic analyzers in these two groups are as follows:

General-Purpose Probing

E5383A 17-channel single-ended flying lead probe

Ideal when only a few lines may need to be probed or probe points are distributed across a target. The E5383A includes a set of 20 IC test clips and five ground leads.

Logic analysis general-purpose probes

General-purpose probing requires connecting probe leads to individual signal lines. This method is most convenient for a small to moderate number of signals, very flexible, and can be used in conjunction with other probing methods.

Note: Any probed signal line must be able to supply a minimum of 600mV to the probe with the specified loading.

Tip Isolation Network Equivalent Load

Figure 2.1. Probe tip Isolation network and equivalent load

The standard probing system

The standard probing system consists of IC clips, probe leads, probe housing and probe cable. Because it is passive, the standard probing system is smaller, lighter, and much easier to use than active probing systems. This passive probing system is similar to a probing system used on a high

Probe leads and lead sets

Probe leads are configured into lead sets, which can probe 16 data channels with ground, one clock channel, and a common ground. A 17-channel probe lead set (E5383A) is shown in Figure 2.2, along with the replacement part numbers for individual

components in Figure 2.3. frequency oscilloscope. It consists of an isolation network (as shown in Figure 2.1) at the probe tip and a shielded resistive transmission line. The advantages of this system are:

• High input impedance. See

Figure2.1.

Each probe lead is a 12-inch, twisted-

pair cable connected to the probe

cable at the probe housing (see

Figure 2.3). The probe tip includes a

signal lead, a connector for a ground

lead, and the isolation network.

• Signal ground at the probe tip for

high-speed signals.

• Inexpensive, removable probe tip

IC clips

The surface-mount device IC clip with twin hooks (part number 5090-4833, containing 20 IC clips) is designed for fine surface-mounted component leads. The twin hook 0.5 mm IC clip (part number 10467-68701, containing four 0.5 mm IC clips), is very useful for 0.5 mm pitch components. See Figure 2.5.

Grounding

There are three methods of grounding the probe system. First, the entire probe lead set can be grounded through the common ground. This requires only one connection, but is not recommended because it will cause poor signal fidelity in systems with fast transition times. The recommended method is to individually ground each probe lead. This yields optimal signal fidelity and is required for signals with faster transition times (< 4 - 5 ns).

Designing for Logic Analysis Probing

Agilent recommends that targets with probing constraints have connectors designed into the prototype versions of the product for effective hardware and software debug. The following should be considered when designing with connectors:

• Select the appropriate connector technology for your target speed and target density.

• Carefully select all lines for routing to the connectors that may be needed for debug.

• Group the lines at each connector for your probing convenience. For example, Agilent may have written an inverse assembler for your device that has a preconfigured signal order. Before designing, refer to the documentation for this inverse assembler for essential signal lines and order.

• Keep the routing to connectors as short as possible to minimize target impact and provide accurate data.

An isolation network must be located between the target and the logic analyzer. It can be located on the target board in through-hole or SMT parts; or it can be attached to the logic analyzer cable with the probe leads (the isolation network is molded into the end of the probe); or the Agilent 01650-63203 isolation adapter with self contained isolation networks can be used. Probe leads can be used with connectors but are not the most convenient method. Direct connection of the connectors with the analyzer cable (isolation network parts on the target) or with a probe or isolation adapter is the faster, more convenient method.

• Examine the impact of probing isolation networks designed into the target versus the isolation network products offered by Agilent Technologies.

Soft Touch Connectorless Probing

High-density, high-performance probes

Agilent Pro Series soft touch connectorless logic analyzer probes

Agilent has developed connectorless logic analyzer probes based on soft touch probing technology. Connectorless logic analyzer probing removes the connector that is traditionally attached to the target board and replaces it with an array of probe pads. This reduces the probe load on the target by eliminating the loading associated with the physical body of the connector. Additionally, this streamlines the design flow by eliminating the need to assign a logic analyzer connector to the bill of material of your board, procuring those connectors and then having them loaded onto your board.

Agilent’s soft touch connectorless probes use micro spring-pin technology to provide reliable contact which is not dependent on the planarity of

the PC board or the plating processes used to fabricate the board. No special cleaning processes are required when using Agilent’s soft touch probes.

The new Agilent Technologies Pro Series soft touch connectorless probes offer a 30% smaller footprint than the original soft touch probes and are the basis for the industry standard connectorless probing footprint.

The probes use a retention module that ensures soft touch pin-to-PC board pad alignment and holds the probe in place while in use. The Pro Series soft touch uses a “top-side” mountable retention module. The retention module is mounted on the same side of the board as the probing footprint so there is no need to access the back-side of the board. Because there is no requirement for the retention module pins to extend beyond the back-side of the board, the retention module is compatible with virtually any board thickness.

E5404A Pro Series soft touch connectorless probe

The E5404A is a 34-channel single-ended Pro Series soft touch connectorless probe compatible with all Agilent logic analyzers that have a 40-pin pod connector. It is capable of acquiring data at the maximum rates of the logic analyzer it is connected to.

• 16 single-ended data inputs

• one single-ended clock input

• < 0.7 pf equivalent load capacitance

• 500 mV p-p minimum signal amplitude

The unused clock input can be used as a data input.

High-Density, High-Performance

Agilent has developed high-density probing solutions based on the 100-pin Samtec and AMP Mictor 38-pin connectors. The Agilent probes and adapter cables, E5346A, E5339A, E5351A, and E5385A provide a connection strategy to route your important signals to the Agilent logic analyzer. Simply design the connectors onto the board for the critical signals

such as address, data, and status bits. The connectors consume a minimal amount of board space. Each connector provides 32 channels of logic analysis per connector and two clocks (unused clocks can be used as data). Connectors for use with the E5385A, E5346A, E5339A, and E5351A can be purchased directly from AMP, Samtec, or Agilent Technologies. See the “Related Information” at the end of this document.

Agilent Technologies E5346A, E5339A, and E5385A probes

The E5346A, E5339A, and E5385A probes include the required isolation networks for the logic analyzer right at the probe tip, close to the target. The E5346A and E5385A are designed to acquire signals with peak-to-peak amplitude as low as 500 mV. The E5339A is designed to acquire signals as small as 250 mV peak-to-peak. Figure 3.18 shows the equivalent load for the E5339A, and Figure

3.19 shows the equivalent load for the E5346A. Figure 3.20 shows the equivalent load for the E5385A.

Equivalent Load

To use the E5346A, E5339A, or E5385A at high clock speeds, the following design guidelines should be observed:

• Calculate the electrical length of the probe hookup stub.

• For PC board material with E

=4.9, use a propagation delay

of 160 ps/inch.

• Check that the propagation delay of the probe hookup stub is less than 20% of the bus signal rise time (T

). If it is, the E5346A,

E5339A, or E5385A can be used for connection.

For example, if E

=4.9, a 2.5 inch

probe hookup stub generates a propagation delay of 400 ps. If Tr is > 2 ns, the E5346A, E5339A, or E5385A is a viable probing choice.

The E5346A and E5339A use the AMP Mictor 38-pin connector. The E5385A uses a 100-pin connector manufactured by Samtec. Agilent recommends the E5394A or E5385A for new applications, due to the reduced input capacitive loading and improved isolation between adjacent channels.

Agilent E5351A 38-pin adapter cable

If the calculated electrical length of the required routing stub prohibits the use of the Agilent E5339A, E5346A, or E5385A, the Agilent E5351A can be used with the required isolation networks installed on the target.

The E5351A does not have its own internal isolation networks. When using the E5351A, place the SIP isolation networks, surface mount isolation network 5062-7396, or equivalent discrete components very near the target component for mea-

surement. Ensure that the stub length between the target component and the isolation network is short. The stub propagation delay should be less than 20% of the bus signal rise time, as mentioned before. The transmission line from the on-board isolation network to the Mictor connector should be designed for an impedance in the range of 80 to 100 ohms (closer to 100 ohms is better). This length should not exceed 3 to 4 inches, and all signal line lengths should be equal. Signal line length variation should not cause propagation delay variation to exceed 20 ps between signal lines.

Notes on using discrete components

Discrete components can be used in the design of the RC network. Agilent recommends the circuit shown in Figure 3.25. To achieve the equivalent load shown in the figure, trace lengths should be minimized by locating the RC network very near the measured node. Actual load will be the stub length load added to the equivalent load in the figure.

Probing Solutions for 40-pin Logic Analyzers

Mictor and Samtec Probing

Options for on-board terminations for the E5351A

There are two options for isolating the E5351A on the target PC board:

• Use the surface mount isolation network, Agilent part number 5062-7396. Refer to Figure 3.26 for schematic and pinout.

• Use discrete components. Refer to Figure 3.25 for recommended components and equivalent load.

If you are operating at state speeds above 200 MHz, you should use discrete components for best results. Due to the added electrical length of the E5351A probe cable, the divider compensating capacitors in the SIP, and surface-mount isolation networks are not optimum for the E5351A, but they are usable up to 200 MHz clock rates.

Notes on using the 5062-7396 SMT part

Agilent currently recommends a two-step process in soldering the SMT part to the board. The first pass places solder paste on those pads with vias. Application of heat allows the via to fill with solder. (If only one solder step is used, the solder wicks away from the part into the via and a solid connection will not be made with the part.) The next pass places solder paste on all of the pads.

As shown in Figure 3.26, the 5062-7396 SMT isolation network supports six logic analysis channels. The size of the part allows you to repeat the pattern in Figure 3.26 to accommodate multiple parts stacked end-to-end for the number of channels needed in your application. Three of these SMTs are required for each

probe cable. The process for using the ceramic hybrid isolation network is similar to the process for an LCC package. Due to the small part size, thermal expansion mismatch during solder reflow should not be a problem. Capacitance also remains stable with temperature changes.

Support shrouds

A support shroud is recom mended to provide additional strain relief between the probe and the connector, as shown in Figures 3.21 and 3.23. Two plated through-holes are required on the target board. The shroud is mounted directly to the target board using the through-holes. This places the shroud around the connector, providing solid mechanical strain relief. Connector kits are available; Table 1 shows the Agilent part numbers for shrouds and connector kits for various PC board thicknesses.

Right-angle Mictor adapter

For systems with space constraints above the 38-pin connector, Agilent offers a right-angle adapter, as shown in Figure 4.1. With the E5346-63201 right-angle adapter inserted in the 38-pin connector, the adapter cable is connected parallel to the target board surface. When using the right-angle adapters, the 38-pin connectors must be placed end-to-end on the target board, as shown in Figure 4.2. Support shrouds cannot be used with the right-angle adapter.

Low density, moderate performance

Solutions shown in the “High-Density, High-Performance” (page 23) section of this document can be used in place of the solutions described here. Agilent recommends standard

0.1inch center connectors for normal

density applications if the loading/ speed is not a significant issue. Many of these items are available from 3M or Agilent (see Table 2). See the “Related Information” section at the end of this document for 3M address information.

Direct connection through isolation adapter

Isolation adapters (Agilent part number 01650-63203) that connect to the end of the probe cable are designed to perform two functions. The first is to reduce the number of pins required for the header on the target board from 40 pins to 20 pins. This process reduces the board area dedicated to the probing connection. The second function is to provide the proper RC networks in a very convenient package. Figure 4.3 illustrates how the isolation adapter physically connects to the target system and the equivalent load of the isolation adapter connected to an Agilent logic analyzer. Figures 4.4 and 4.5 show the pinout diagrams for the probe cable and the isolation adapter, respectively. There are two 20-pin connectors, along with their Agilent and 3M part numbers, listed in Table 2.

Direct connection through 40-pin connectors

The probe cable also can be plugged directly into the various 40-pin connectors shown in Table 3, but proper isolation networks must be installed directly onto the target system board (see Figure 4.6 for the 40-pin connector pinout).

Agilent offers a 12-pin SMT (Agilent part number 5062-7396), which provides six isolation networks, as shown in Figure 4.7. Three of these SMTs are required for each probe cable.

Discrete components can also be used for the proper isolation network. See Figure 4.9 for an equivalent load diagram for the isolation networks.

Note that the effective input capacitive lead of an isolation network using discrete components is a function of the layout geometry and the parasitic capacitance of the input series damping resistor.

Notes on using discrete components

Discrete components can be used to design the isolation network. Agilent recommends the circuit shown in Figure 4.9. To achieve the equivalent load shown in the figure, trace lengths should be minimized by locating the RC network very near the measured node. Actual load will be the stub length load added to the equivalent load in the figure. Trace length from the suggested on-board RC network to the target connector must be 3 to 4 inches or less. This transmission line should be designed for an impedance in the range of 80 to 100 ohms (closer to 100 ohms is better).

Soft Touch Connectorless Probing

Seven options are available for connecting Agilent logic analyzers with 90-pin pod connectors to a target system using mass connections.

Agilent Pro Series soft touch connectorless logic analyzer probes

this streamlines the design flow by eliminating the need to assign a logic analyzer connector to the bill of material of your board, procuring those connectors and then having them loaded onto your board.

Agilent’s soft touch connectorless probes use micro spring-pin technology to provide reliable contact which is not dependent on the planarity of the PC board or the plating processes used to fabricate the board. No special cleaning processes are required when using Agilent’s soft touch probes.

The new Agilent Pro Series soft touch connectorless probes offer a 30% smaller footprint than the original soft

touch probes and are the basis for the industry standard connectorless probing footprint.

Wedge adapters

The Agilent Technologies Wedge technology provides very reliable probing of a few channels on 0.5 mm and 0.65 mm pitch QFPs. No clear area is required around the device. Each Wedge of the probe slides between the legs of the QFP. The side of each Wedge probe contacts the package legs. An insulation core electrically isolates the sides of each Wedge (see Figures 9.1 and 9.2). Various 3-signal, 8-signal, and 16-signal probes are available (see Table 9).
