GoLogic-U72-1M - NCI Logic Analyzers

NCI GoLogic-U72-1M Overview

• Number of channels - 72 or 36 depending on model
• Memory depth (72 channel models) - 1M version: 1,048,576 samples across all channels. Double-depth option increases the depth to 2,097,152 samples. Transitional timing and state analysis with time stamp halve the memory depth to 524,288 samples. 2M version: 2,097,152 samples across all channels. Double-depth option increases the depth to 4,194,304samples. Transitional timing and state analysis with time stamp halve the memory depth to 1,048,576 samples
• Memory depth (36 channel models) - 2M version: 2,097,152 samples per channel. Transitional timing and state analysis with time stamp halve the memory depth to 1,048,576 samples. Double-depth option not available. 4M version: 4,194,304 samples per channel. Transitional timing and state analysis with time stamp halve the memory depth to 2,097,152 samples
• Probe inputs - 240 Kohm input impedance shunted by 10 picofarads. 1 nanosecond maximum skew between channels 2 nanosecond setup time with 0 nanosecond hold time
• Threshold levels - One independent threshold level per 16 channels. Variable between -4.90 volts and +5.27 volts in about 40 millivolt increments. Voltage swings as low as 600 millivolts are supported
• Minimum input voltage range - 0.6 volt peak to peak around the threshold voltage. Minimum high level is 0.3 volt above threshold voltage. Minimum low level is 0.3 volt below threshold voltage
• Clock channels - 4 clock channels are available when using state analysis
• Minimum sampling rate - 500 Hz timing analysis. No minimum rate for state analysis
• Maximum sampling rate - 500 MHz timing analysis. 125 MHz with state analysis. Actual maximum state analysis sampling rate is determined by the source clock’s signal quality
• Trigger patterns - 8 normal trigger patterns plus 2 edge events (timing analysis) or 2 range events (state analysis)
• Sequence levels - 8 sequence levels. 2 patterns + 2 edge/range per sequence level
• Sequence counter - One 20-bit counter per sequence level. Minimum counter value is 2 and maximum is 1,046,575
• Sequence timer - See Global timer limits and Level timer limits appendices for a table of the minimum and maximum timer values for each sampling rate
• Trigger-out signal - The trigger-out signal uses TTL logic. The connector outputs an active low signal. The signal goes low when the logic analyzer triggers
• Dimensions - Width: 3.8" (9.5 cm); Length: 6.3" (16 cm); Height: 1.2" (3 cm); Weight: 14 oz. (410 grams)
