Tektronix Logic Analyzers

TLA7N4 Logic Analyzer Module

Characteristics

General

Number of Channels (all channels are acquired including clocks) - TLA7N4: 136 channels (4 are clock and 4 are qualifier channels).

Channel Grouping - No limit to number of groups or number of channels per group (all channels can be reused in multiple groups).

Module "Merging" - Three modules can be "merged" to make up to a 408-Channel module. Merged modules exhibit the same depth as the lesser of the three individual modules. Word/range/setup-and-hold/glitch/transition recognizers span all three modules. Only one set of clock connections is required.

Time Stamp - 50-Bit at 500 ps resolution (6.5 day range).

Clocking/Acquisition Modes - Internal, internal 2X, external. 2 GHz MagniVu high-speed timing is available simultaneous with all modes.

Number of Mainframe Slots Required per TLA Series Module -  2.

Input Characteristics (with P6417, P6418, P6419, or P6434 probes)

Capacitive Loading -

<0.7 pF data and clock (P6419).

Input Voltage Range - Operating: 6.5 V_p-p centered around the programmed threshold.

Non-destructive: ±15 V.

Minimum Input Signal Swing - 250 mV or 25% of signal swing, whichever is greater (P6417, P6418, & P6419).

300 mV or 25% of signal swing (P6434).

Input Signal Minimum Slew Rate - 200 mV/ns typical.

State Acquisition Characteristics (with P6417, P6418, P6419, or P6434 probes)

State Clock Rate - 100 MHz standard, 200 MHz optional.

State Memory Depth with Timestamps - 64 Kb, 256 Kb, 1 Mb, or 4 Mb per channel.

Setup-and-hold Time Selection Range - From 8.5 ns before, to 7.0 ns after clock edge.

Setup-and-hold Window - 2 ns typical.

Minimum Clock Pulse Width - 2 ns.

Active Clock Edge Separation - 5 ns.

Demux Channel Selection - Channels can be demultiplexed to other channels through user interface with 8-Channel granularity.

Timing Acquisition Characteristics (with P6417, P6418, P6419, or P6434 probes)

MagniVu™ Timing - 500 ps.

MagniVu Timing Memory Depth - 2 Kb (2048) per channel.

Deep Timing Resolution (half/full channels) - 2/4 ns to 50 ms.

Deep Timing Resolution with Glitch Storage Enabled - 10 ns to 50 ms.

Deep Timing Memory Depth (half/full channels with timestamps and with or without transitional storage) - 128/64 Kb, 512/256 Kb, 2/1 Mb, 8/4 Mb per channel.

Deep Timing Memory Depth with Glitch Storage Enabled - Half of default main memory depth.

Channel-to-channel Skew - <1 ns typical.

Minimum Recognizable Pulse Width (single channel) - 2 ns.

Minimum Recognizable Glitch Width (single channel) - 2 ns.

Minimum Recognizable Multi-channel Trigger Event - Sample period +2 ns.

Trigger Characteristics

Independent Trigger States -  16.

Maximum Independent If/then Clauses per State -  16.

Maximum Number of Events per If/then Clause -  8.

Maximum Number of Actions per If/then Clause -  8.

Maximum Number of Trigger Events - 18 (2 counter/timers plus any 16 other resources).

Number of Word Recognizers -  16.

Number of Range Recognizers -  4.

Number of Transition Recognizers -  1.

Number of Counter/Timers -  2.

Trigger Event Types - Word, group, channel, transition, range, anything, counter value, timer value, signal, glitch, setup-and-hold violation.

Trigger Action Types - Trigger module, trigger all, store, don't store, start store, stop store, increment counter, reset counter, start timer, stop timer, reset timer, goto state, set/clear signal, do nothing.

Trigger Sequence Rate - DC to 250 MHz (4 ns).

Counter/Timer Range - 51 Bits each (>100 days at 4 ns).

Counter Rate - DC to 250 MHz (4 ns).

Timer Clock Rate - 250 MHz (4 ns).

Counter/Timer Latency - None (can be tested or reset immediately after starting).

Range Recognizers - Double bounded (can be as wide as any group, must be grouped according to specified order of significance).

Setup-and-hold Violation Recognizer Setup Time Range - From 8 ns before to 7 ns after clock edge in 0.5 ns increments.

Setup-and-hold Violation Recognizer Hold Time Range - From 7 ns before to 8 ns after clock edge in 0.5 ns increments.

Trigger Position - Any data sample.

MagniVu Trigger Position - MagniVu data is centered around the module trigger.

Storage Control (data qualification) - Global (conditional), by state (start/stop), by trigger action, or transitional.

Storage Window Granularity - Single sample or block-of-31 samples before and after.

Safety - CSA C22.2 No. 1010.1, EN61010-1, IEC61010-1, UL 3111-1
