During RFQ preparation, TPS can help the buyer evaluate whether 350MHz is sufficient or whether the 500MHz model gives the safer engineering margin.<\/p>\n<h3 id=\"en-memory-and-capture\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">Use memory depth and segmented storage to capture long or intermittent events<\/h3>\n<p style=\"margin: 0 0 14px 0;\">Deep memory is important when engineers need to zoom into a long acquisition without losing signal fidelity. The ETO Series supports up to 360Mpts memory depth and segmented storage for up to 10,000 events. In practical terms, this helps capture intermittent switching events, serial bus faults, laser pulse timing, start-up behavior, relay transients and communication errors that may not appear in a short acquisition window.<\/p>\n<h3 id=\"en-triggering-and-bus-decode\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">Confirm trigger and bus decoding requirements before ordering<\/h3>\n<p style=\"margin: 0 0 14px 0;\">Trigger types include edge, pulse width, logic, Nth edge, runt, slope, time out, video and serial bus triggering. Serial bus decoding supports RS-232\/422\/485\/UART, CAN, CAN FD, LIN, SPI, I2C, ARINC-429 and MIL-STD-1553B. For procurement, this means the RFQ should not only state \u201c4-channel oscilloscope.\u201d It should also list the protocols, voltage levels, probe types and analysis workflows that need to be supported.<\/p>\n<\/section>\n<div style=\"display: flex; flex-wrap: wrap; gap: 18px; align-items: center; border: 1px solid #e5e7eb; background: #f9fafb; padding: 16px; margin: 30px 0; border-radius: 10px;\">\n<div style=\"flex: 1 1 300px;\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 8px;\" src=\"https:\/\/www.shop-tps.com\/web\/image\/product.template\/34023\/image_1920?unique=59c2509\" alt=\"ETO5004 500MHz four-channel tablet oscilloscope for advanced signal analysis\" \/><\/div>\n<div style=\"flex: 1 1 300px;\">\n<h3 id=\"en-image-eto5004-bandwidth\" style=\"font-size: 21px; margin: 0 0 10px 0; color: #111827;\">500MHz option for higher bandwidth margin<\/h3>\n<p style=\"margin: 0;\">Where faster transient behavior, higher-frequency signal content or future test requirements are expected, the 500MHz version can provide additional measurement headroom.

The ETO Series supports hardware digital filtering, advanced math functions, FFT analysis, statistical measurement and file saving in formats such as CSV, BIN and WAV. This makes it suitable for circuit debugging, power electronics checks, communication line analysis and validation workflows where data export matters.<\/p>\n<h3 id=\"en-fit-system-integrators\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">For system integrators: remote control, SCPI and repeatable test workflows<\/h3>\n<p style=\"margin: 0 0 14px 0;\">For system integrators, the oscilloscope must often become part of a repeatable test environment. The ETO Series supports PC and mobile remote control, HDMI projection and SCPI commands. This is useful when the oscilloscope is used near a test rack, in a service station, or in a power electronics validation bench. TPS can also help connect the oscilloscope discussion to related test equipment, such as <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/ea-ps-3200-02-c-desktop-programmable-dc-power-supply\/\">desktop programmable DC power supplies<\/a>, <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/ea-psi-9000-dt-desktop-programmable-dc-power-supply\/\">higher-performance programmable DC sources<\/a> or a <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/ea-pul-10000-6u-regenerative-dc-load\/\">regenerative DC load<\/a>.<\/p>\n<h3 id=\"en-fit-panel-builders-procurement\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">For panel builders and procurement: practical handling, documentation and supplier response<\/h3>\n<p style=\"margin: 0 0 14px 0;\">Panel builders and procurement teams need clear product data, accessory lists, compliance documentation, quotation validity and delivery coordination. The ETO Series has a 75 x 75mm VESA mount interface, multiple physical interfaces and standard accessories such as passive probes, probe adapters, power adapter, power cord, built-in battery, side handle, calibration certificate, quick guide, packing list and user instructions. For mixed projects, TPS can also support related infrastructure, including <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/tps030-130w-pro-series-din-rail-power-supply\/\">DIN rail power supplies<\/a>, <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/6u-19-inch-chassis-power-supply-integration\/\">19-inch chassis integration<\/a> and <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/sentinel-y-24u-cabinet-19-inch-power-integration\/\">19-inch cabinet power integration<\/a>.<\/p>\n<\/section>\n<section>\n<h2 id=\"en-integration-installation\" style=\"font-size: 27px; line-height: 1.3; margin: 34px 0 14px 0; color: #111827;\">Integration, installation and accessory considerations<\/h2>\n<p style=\"margin: 0 0 14px 0;\">The ETO Series is not limited to classic bench use. The 14-inch integrated touch display supports fast interaction, while the physical interface set supports a wide range of workflows: USB 3.0 host, USB 2.0 host, USB Type-C, HDMI, trigger out, grounding and DC power input. Adapter input is 100-240VAC, 50\/60Hz, with power consumption below 84W and 12VDC \/ 7A adapter output. Operating temperature is specified from 0\u00b0C to 45\u00b0C, which should be checked against the project\u2019s service environment.<\/p>\n<p style=\"margin: 0 0 14px 0;\">Probe planning is equally important. Standard passive probes may be sufficient for many general-purpose measurements, but high-voltage, differential, current or isolated measurements may require dedicated optional probes. For power electronics projects involving bidirectional converters, battery systems or load testing, TPS can help align oscilloscope selection with related power modules such as <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/tps-bm75053ktif-s-750v-bidirectional-power-module\/\">750V bidirectional power modules<\/a> or <a style=\"color: #0057a8; text-decoration: none;\" href=\"https:\/\/tps-elektronik.com\/en\/ac-dc-bidirectional-power-modules-cell-formation-14v\/\">AC-DC bidirectional modules for cell formation<\/a>.<\/p>\n<\/section>\n<div style=\"display: flex; flex-wrap: wrap; gap: 18px; align-items: center; border: 1px solid #e5e7eb; background: #ffffff; padding: 16px; margin: 30px 0; border-radius: 10px;\">\n<div style=\"flex: 1 1 300px;\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 8px;\" src=\"https:\/\/www.shop-tps.com\/web\/image\/product.template\/28045\/image_1920?unique=9948ac3\" alt=\"ETO Series oscilloscope with touch display for integration and service workflows\" \/><\/div>\n<div style=\"flex: 1 1 300px;\">\n<h3 id=\"en-image-integration-considerations\" style=\"font-size: 21px; margin: 0 0 10px 0; color: #111827;\">RFQ note: define the complete measuring chain<\/h3>\n<p style=\"margin: 0;\">A professional RFQ should define the oscilloscope, probes, adapters, calibration documentation, software\/remote-control needs, delivery destination and after-sales contact route.

TPS can review your application before quotation.<\/p>\n<h3 id=\"en-faq-field-use\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">Is the ETO Series suitable for field service?<\/h3>\n<p style=\"margin: 0 0 14px 0;\">Yes. The tablet format, built-in battery, large touch display and remote-control options make the ETO Series suitable for field diagnostics, service work and mobile engineering tasks, provided the operating environment matches the specified conditions.<\/p>\n<h3 id=\"en-faq-probes\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">Should probes be included in the RFQ?<\/h3>\n<p style=\"margin: 0 0 14px 0;\">Yes. The oscilloscope is only one part of the measuring chain. Include passive probes, differential probes, current probes or isolated probes if your application requires them. TPS can help define the accessory set.<\/p>\n<h3 id=\"en-faq-automation\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">Can the ETO Series support automated testing?<\/h3>\n<p style=\"margin: 0 0 14px 0;\">The ETO Series supports SCPI commands and remote-control workflows, which can be useful for repeatable engineering tests and system integration. For larger validation benches, TPS can also advise on related power supplies, loads and cabinet or chassis integration.<\/p>\n<h3 id=\"en-faq-rfq-info\" style=\"font-size: 21px; margin: 20px 0 8px 0; color: #111827;\">What information should procurement send to TPS?<\/h3>\n<p style=\"margin: 0;\">Please send the target model, quantity, delivery country, application, required protocols, probe\/accessory needs, documentation requirements and expected delivery date.
