# Keysight 34190A Rackmount Adapter Kit, 88.1 mm H (2U), for Half-Width Modules (Pre-Owned) # Keysight 34190A Rackmount Adapter Kit, 88.1 mm H (2U), for Half-Width Modules (Pre-Owned) ## Key Features At A Glance - Comprehensive cross-reference covering rackmount flanges, handle kits, and adapter kits across hundreds of Keysight, Agilent, and HP instrument models - Standard flanges with 1.75 in hole spacing and special flanges with 3 in hole spacing to match System II instrument case patterns - Five product families: 1CP rackmount flanges with handles, 1CM rackmount flanges (with and without handle cutouts), 1CM adapter kits, and 1CN handle kits - Coverage for instrument module heights of 88.1 mm (2U), 132.6 mm (3U), 177.0 mm (4U), 221.5 mm (5U), 265.9 mm (6U), and 310.4 mm (7U) - Adapter kits accommodate quarter-width, half-width, and three-quarter-width modules for side-by-side mounting in 19-inch racks - Kits ship with mounting screws and metric fasteners; lock link kit (5061-9694) required for side-by-side modules of equal depth - Each accessory cross-referenced to the original instrument option code (e.g., 1CM, 1CN, 1CP, 908, 909) used at time of instrument order The Keysight Rackmount Accessory Products Cross Reference Guide is a selection reference designed to help engineers and procurement teams identify the correct rackmount hardware for a specific Keysight, Agilent, or HP test and measurement instrument. The guide is organized so that a user identifies the instrument needing the rackmount accessory, then looks across columns corresponding to handles, rackmount flanges, rackmount flanges for units with existing handles, adapter kits with filler panel, rackmount kits including handles, and rack slides to find the correct part number to order. Each entry lists the original instrument option code, the primary component part number, and a descriptive accessory product name. The accessories documented in this guide support standard System II instrument cases by attaching to pre-existing holes in the instrument chassis. Customers use these kits to maneuver and securely mount instruments into standard 19-inch rack enclosures for production test systems, ATE configurations, environmental test setups, and permanent bench installations. The guide covers handle-only kits for easier carrying, rackmount flange kits for mounting without handles, combined flange-and-handle kits, and specialized adapter kits that mount quarter-width and half-width modules side by side within a full rack opening. ValueTronics International stocks Keysight, Agilent, and HP rackmount accessories along with the test and measurement instruments they support. All inventory is stored and tested in our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. When customers order an instrument together with its rackmount kit, our team can confirm the correct flange, handle, or adapter part number against the original instrument option code so the hardware arrives matched to the case hole pattern. ## Brand Heritage Hewlett-Packard's test and measurement business was spun out as Agilent Technologies in 1999, and the electronic measurement portion of Agilent was transferred to Keysight Technologies in 2014. This document spans all three brand eras: instruments originally sold under HP and Agilent designations are cross-referenced to the same accessory part numbers now issued under the Keysight brand, with the underlying mechanical hardware and option codes preserved across the transitions. ## Compare Other Models in This Series The Rackmount Accessory Products line is organized as a cross-reference guide rather than a single instrument family. It documents the relationships between Keysight, Agilent, and HP instruments and the rackmount flanges, handle kits, adapter kits, and combined flange-and-handle kits that fit each instrument's case dimensions and hole patterns. Customers entering this catalog typically start with a specific instrument model number — for example, an oscilloscope, signal generator, power supply, or spectrum analyzer — and use the technical specifications table to find the corresponding accessory part number. The guide also documents the original option codes (1CM, 1CN, 1CP, 907, 908, 909, and others) so that an instrument ordered years ago with a specific factory option can be matched to the current standalone replacement accessory. Each rackmount accessory listed below is its own product page with pre-owned-matched pricing and availability. If you have located an instrument and need the corresponding flange, handle, or adapter, use the technical specifications table in this guide to find the accessory part number, then locate that accessory on its own product page to confirm current pricing and stock. The five accessory families differ by what they include and which instruments they fit. The 1CN handle kits add two front handles to instruments that did not ship with them, attaching to pre-existing case holes after the customer removes a plastic trim strip. The 1CM flange kits provide two rackmount flanges with no notch for handles, intended for instruments mounted in racks without front carrying handles. The 1CM kits for instruments with previously supplied handles include a special cutout in each flange to accommodate the existing handles. Module height is the second axis of differentiation. The guide covers 88.1 mm (2U), 132.6 mm (3U), 177.0 mm (4U), 221.5 mm (5U), 265.9 mm (6U), and 310.4 mm (7U) instrument heights, with the corresponding flange dimensions sized to each height. The comparison table that follows lists each accessory part number against the instrument height and the included components.

Side-by-Side Mounting Side-by-side modules of equal depth require a lock link kit (5061-9694) **Important:** The following kits use standard flanges with 1.75 in hole spacing: 5063-9212, 5063-9219, 5063-9232. The following kits use special flanges with 3 in hole spacing: 5063-9213, 5063-9220. Side-by-side modules of equal depth require a lock link kit (5061-9694).**Important:** Flanges attach to pre-existing holes in the instrument case.**Important:** Before rack mounting, bottom feet must be removed.**Important:** Side-by-side modules of equal depth require a lock link kit (5061-9694).**Important:** 1CM Series rackmount flange kits without a handle notch will not fit onto instruments with previously supplied handles; for those instruments use the 1CM Series kits designed for units with previously supplied handles.**Important:** Use the Keysight Rackmount Accessory Cross Reference Selection Guide to identify the correct accessory for a specific instrument by locating the instrument model and the corresponding accessory product number in the appropriate column.Usage tip: a quarter-module flange can be center-mounted in a full-rack opening using two of the adapter kits described in this guide, per the 1CM Series Rackmount Adapter Kits section. ## About this used unit - Warranty included - Functional verification included - Note that unnecessary accessories may not be included (contact Test Architect to confirm). **Please review the Manufacturer's Data Sheet to verify published specifications.
