About the comparison tables
™
The comparison tables illustrate how extremely cost effective the GoLogicXL is compared with Agilent® and
Tektronix® logic analyzer products offering similar capabilities.
The latest Agilent® and Tektronix® logic analyzer models were chosen to best match the GoLogicXL's features such
as channels, sampling rates, sample depths, triggering, and so forth. Flying lead set probes were selected for all logic
analyzers in this comparison. Memory options for competitor products were chosen to best match the GoLogicXL's
mid memory option. The GoLogicXL large memory upgrade doubles the maximum sample depths for an additional
$2,000 US.
Agilent® and Tektronix® logic analyzer models are self-contained. The GoLogicXL requires a laptop or desktop

Glossary
October 15, 2014
Normal Timing mode oversamples the input signals similar to how an oscilloscope recreates an analog
signal. However, only the logic-levels are captured rather than voltage-levels.
Transitional Timing mode is identical to Normal Timing except the logic analyzer stores the input signals
to memory only when a change occurs. This eliminates all redundant samples between signal-changes. A
timestamp is stored with each sample so the elapsed time between signal-changes is known.
High-speed overlay is a relatively narrow burst of high-speed Normal Timing trace captured alongside
the main trace capture across all channels. The overlay data provides a relatively small window of higher
resolution trace which is centered at the trigger.
Differential input mode combines two input signals to produce one signal. This halves the available
input channels. For example, the GoLogicXL-72 captures up to 36 signals when differential input mode is
active. Unlike Keysight/Agilent and Tektronix analyzers, the GoLogicXL does not require special probes
to capture differential signals.
Glitch triggers: While running, the logic analyzer triggers if two or more transitions occur on a signal
between logic analyzer samples. Channels that detect glitch events can be enabled or disabled. Likewise,
the glitch detection can be enabled or disabled on different trigger sequence levels.
Glitch capture is a special sampling mode where the logic analyzer marks all glitch events in the trace
data. Since glitches are between samples, no pulse is visible in the timing diagrams. Instead, a special
mark is drawn on the data to show where the glitch occurred.
Setup/Hold triggers allow a setup/hold condition to be specified. While running, the logic analyzer
triggers when the setup/hold condition for any channel is violated.
Selective storage: While running, each level of the trigger sequence can store all incoming data to
memory, store only data that matches certain patterns, or can ignore all incoming data.
Flying lead set probe: The most flexible probing option. Individual channels can be connected to a
variety of input types. Normally pressed directly onto 25 mm (0.10”) header pins, gripper probes can also
be used to attach each input to chip pins or exposed wires. The GoLogicXL standard lead sets are
coaxially shielded, have a ground input per each channel, and are color-coded for fast access.
Mictor is an acronym for Matched Impedance ConnecTOR. This board-to-board connector was
developed by TE Connectivity / AMP corporation in the 1990s. The 38-pin variant of the connector is
commonly used by logic analyzers to probe high-speed signals due to its low impedance nature. The
pads for the female Mictor connector are included in a device’s printed circuit layout. The female Mictor
connector can then be soldered to the device. The NCI Mictor probes are pin-compatible with similar
probes from Keysight/Agilent and Tektronix.
Connectorless probing is a high-speed, low-capacitive-load system. Two rows of pads are designed into
the PCB. Four though-holes around the pads allow a “retention module” to be attached to the PCB when
needed. The logic analyzer probe is inserted into the retention module. Tiny springs press probes directly
against the pads. The NCI PinPoint™ probes are pin-compatible with similar probes from Keysight/Agilent
and Tektronix.
