It is useful for systems that need to monitor many conditioned sensor and voltage signals from one USB connection.<\/p>\n<p>The 250 kS\/s rate is shared by all active channels. With 32 channels sampled evenly, the achievable rate per channel is lower than the aggregate device rate.<\/p>\n<h3>Screw-Terminal and BNC Versions<\/h3>\n<p>The screw-terminal version is appropriate for permanent or semi-permanent multiwire installations. The BNC version simplifies connection to oscilloscopes, laboratory sensors and other coaxial equipment.<\/p>\n<p>Confirm the exact connector style before purchasing because cables and fixture wiring are not interchangeable between the two versions.<\/p>\n<h2>USB-6218 Applications<\/h2>\n<ul>\n<li>High-channel-count voltage acquisition<\/li>\n<li>Industrial equipment monitoring<\/li>\n<li>Laboratory sensor measurement<\/li>\n<li>Environmental test systems<\/li>\n<li>Production fixture monitoring<\/li>\n<li>Portable multichannel data logging<\/li>\n<li>Ground-loop-sensitive measurements<\/li>\n<li>Mixed analog and digital control<\/li>\n<\/ul>\n<h3>High-Channel-Count Data Logging<\/h3>\n<p>The USB-6218 can collect conditioned voltage signals from as many as 32 sources. It is suitable for temperature, pressure, position and process measurements when the sensors provide compatible voltage outputs.<\/p>\n<h3>Environmental Testing<\/h3>\n<p>Multiple sensor outputs can be monitored during temperature, vibration or reliability testing. The analog outputs and digital lines can also coordinate compatible external equipment.<\/p>\n<h2>USB-6218 Installation Workflow<\/h2>\n<h4>Step 1: Select the Connector Style<\/h4>\n<p>Choose the screw-terminal version for dense wiring or the BNC version for direct coaxial connections.<\/p>\n<h4>Step 2: Install NI-DAQmx<\/h4>\n<p>Install the driver and confirm compatibility with the selected operating system.<\/p>\n<h4>Step 3: Plan Channel Assignments<\/h4>\n<p>Determine which channels use differential or single-ended wiring and calculate the required per-channel sampling rate.<\/p>\n<h4>Step 4: Connect Signals<\/h4>\n<p>Follow the pinout for the exact USB-6218 version and keep analog cables away from high-current wiring.<\/p>\n<h4>Step 5: Verify the Device<\/h4>\n<p>Run a self-test and test-panel measurement in NI MAX.<\/p>\n<h4>Step 6: Validate the Complete Scan<\/h4>\n<p>Acquire every intended channel and check channel order, scaling, settling, noise and data-storage performance.<\/p>\n<h2>USB-6218 Troubleshooting<\/h2>\n<h4>The Per-Channel Rate Is Lower Than Expected<\/h4>\n<p>The 250 kS\/s specification is aggregate. Divide the available rate among the active channels when planning the scan.<\/p>\n<h4>Some Channels Show Signals from Adjacent Channels<\/h4>\n<p>Review source impedance, wiring, channel order and settling time. High-impedance sources may require buffering.<\/p>\n<h4>The BNC Channel Names Do Not Match the Application<\/h4>\n<p>Verify the physical connector labels and NI-DAQmx channel configuration for the BNC version.<\/p>\n<h4>The Measurement Contains Ground-Loop Noise<\/h4>\n<p>Confirm the isolation boundaries, shielding, terminal configuration and sensor grounding.<\/p>\n<h4>The USB Connection Is Unstable<\/h4>\n<p>Use a short, high-quality cable and connect directly to the computer. Disable inappropriate USB power-saving settings.<\/p>\n<h2>USB-6218 Comparison<\/h2>\n<table>\n<tbody>\n<tr>\n<th>\u041c\u043e\u0434\u0435\u043b\u044c<\/th>\n<th>Analog Inputs<\/th>\n<th>Maximum AI Rate<\/th>\n<th>\u0426\u0438\u0444\u0440\u043e\u0432\u043e\u0439 \u0432\u0432\u043e\u0434-\u0432\u044b\u0432\u043e\u0434<\/th>\n<\/tr>\n<tr>\n<td>USB-6215<\/td>\n<td>16<\/td>\n<td>250 kS\/s<\/td>\n<td>8 lines<\/td>\n<\/tr>\n<tr>\n<td>USB-6216<\/td>\n<td>16<\/td>\n<td>400 kS\/s<\/td>\n<td>Up to 32 lines<\/td>\n<\/tr>\n<tr>\n<td>USB-6218<\/td>\n<td>32<\/td>\n<td>250 kS\/s<\/td>\n<td>16 lines<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Choose the USB-6218 when high analog input density is the primary requirement.
