Specifications

Characteristic Tables

This chapter contains the specifications for the logic analyzer and for the adjustment/verification fixture.

All specifications are guaranteed unless noted Typical. T ypical characteristics describe typical or average performance and provide useful reference information.

Specifications that are check marked with the n symbol are checked directly (or indirectly) in the Performance Verification chapter of this manual.

The specifications apply to all versions of the TLA600 series logic analyzer unless otherwise noted.

The performance limits in this specification are valid with these conditions:

H The logic analyzer must be in an environment with temperature, altitude,

humidity, and vibration within the operating limits described in these specifications.

H The logic analyzer must have had a warm-up period of at least 30 minutes.

All system trigger and external signal input latencies are measured from a falling-edge transition (active true low) with signals measured in the wired-OR configuration.

In the Waveform window, triggers are always marked immediately except when delayed to the first sample. In the Listing window, triggers are always marked on the next sample period following their occurrence.

“Clk” represents the time to the next master clock at the destination logic analyzer. In the asynchronous (or internal) clock mode, this represents the delta time to the next sample clock beyond the minimum asynchronous rate of 4 ns. In the synchronous (or external) clock mode, this represents the tim e to the next master clock generated by the setup of the clocking state machine and the supplied system under test clocks and qualification data.

Signals 1 and 2 (ECLTRG0, 1) are limited to a “broadcast” mode of operation, where only one source is allowed to drive the signal node at any one time. That single source may be utilized to drive any combination of destinations.

SMPL represents the time from the event at the probe tip inputs to the next valid data sample. In the Normal Internal clock mode, this represents the delta time to the next sample clock. In the MagniVu Internal clock mode, this represents 500 ps or less. In the External clock mode, this represents the time to the next master clock generated by the setup of the clocking state machine, the system-under-test supplied clocks, and the qualification data.

Maximum window size = Maximum channel-to-channel skew + (2 x sample

Examples: for P6417 or a P6418 probe and user interface

setup and hold of 2.0/0.0 typical: Maximum window size = 1.6 ns + (2 x 500 ps) + 0.4ns = 3.0 ns Maximum setup time = 2.0 ns + 0.8 ns = 2.8 ns Maximum hold time = 0.0 ns + 0.2 ns = 0.2ns

Channel-to-channel skew (typical) + (2 x sample uncertaint y)

Example: for P6417 or P6418 Probe = 1 ns + (2 x 500 ps) = 2 ns

Setup and hold window range The setup and hold window can be moved for each channel group from +8.5 ns (Ts) to

--7.0 ns (Ts) in 0.5 ns steps (setup time). Hold time follows the setup time by the setup and hold window size.

Specifications

Table 1- 5: TLA600 clocking (Cont.)

Characteristic Description

Clocking state machine

Pipeline delays Each channel group can be programmed with a pipeline delay of 0 through 3 active

clock edges.

It is possible to use storage control and only store data when it has changed (transitional storage).

Applies to asynchronous clocking only. Setup and hold window specification applies to synchronous clocki ng only.

Any or all of the clock channels may be enabled. For an enabled clock channel, either the rising, falling, or both edges can be selected as the active clock edges. The clock channels are stored.

Full and half speed modes are controlled by PowerFlex options and upgrade kits.

All qualifier channels are stored. For custom clocking there are an additional 4 qualifier channel s on C2 3:0 regardless of channel width.

Word/Range recognizers 16 word recognizers. The word recognizers can be combined to form full width, double

bounded, range recognizers. The following selections are available:

16 word recognizers 0 range recognizers 13 word recognizers 1 range recognizer 10 word recognizers 2 range recognizers 7 word recognizers 3 range recognizers 4 word recognizers 4 range recognizers

Range recognizer channel order From most-significant probe group to least-significant probe group: C3 C2 C1 C0 E3

Missing channels for modules with fewer than 136 channels are omitted.

Glitch detector

Minimum detectable glitch pulse wi dth

1,2

Each channel group can be enabl ed to detect a glitch

2.0 ns (single channel with P6417, P6418, or a P6434 probe)

(Typical)

Setup and hold violation detector

1,3

Each channel group can be enabled to detect a setup and hold violation. The range is from 8 ns before the clock edge to 8 ns after the clock edge. The range can be selected in 0.5 ns increments.

The setup and hold violation of each window can be individually programmed.

Transition detector

Each channel group can be enabled or disabled to detect a transition between the current valid dat a sampl e and the previous valid data sample.

This mode can be used to create transitional storage selections where all channels are enabled.

seconds or 104 days.

Counters and timers can be set, reset, or tested and have zero reset latency.

External Signal In

A backplane input signal

External Trigger In A backplane input signal that causes the main acquisition and the MagniVu

acquisition to trigger if they are not already triggered

Active trigger resources 16 maximum (excluding counter/timers)

Word recognizers are traded off one-by-one as External Signal In, glitch detection, setup and hold detection, or transition detecti on resources are added.

Trigger machine actions

Main acquisition trigger Triggers the main acquisition memory

Main trigger position Trigger position is programmable to any data sample (4 ns boundaries)

MagniVu acquisition trigger Triggering of MagniVu memory is controlled by the main acquisition trigger

MagniVu trigger position The MagniVu trigger position is programmable within 4 ns boundaries and separate

from the main acquisition memory trigger position.

Increment counter Either of the two counter/timers used as counters can be incremental.

Start/Stop timer Either of the t wo counter/t imers used as timers can be started or stopped.

Reset counter/timer Either of the t wo counter/t imers can be reset.

When a counter/timer is used as a timer and is reset, the timer continues from the started or stopped state that it was in prior to the reset.

Signal out A signal sent to the backplane to be used by other instruments

Trigger out A trigger out signal sent to t he backplane to trigger other instruments
