Cable Management

G18 Slide Configuration


Slide mount configurations, popular for use with PXI-based testers, offer short cable lengths, easy access to instrumentation, and the ability to connect to secondary instrumentation. In addition, the cabling remains static and electrically consistent when accessing instrumentation. Two considerations should be made when choosing this type of interface: 1) Will the instrument chassis be placed on an instrument bracket? If so, the cables connecting to the receiver should be secured to the strain relief included on the instrument bracket. This prevents the cables from being damaged when the slides are extended. The recommended cable length is 20" when the instrument bracket is used with a slide-mounted receiver.
This length can change if the instrument is being wired to a receiver module on the opposite side of the tester. VPC standard lengths are 20” and 36”; custom lengths are available. 2) Will any instrumentation be located somewhere other than on the instrument bracket? If so, the cables used to connect this instrumentation to the receiver must be long enough to allow the slides to extend fully without putting tension on the cables. To determine the appropriate cable length, measure the vertical distance from the receiver to the instrument, then measure the distance from the front of the rack to the receiver with the slides fully extended, taking into account any bends and special routing considerations. Cables routed to instrumentation not placed on the instrument bracket should be secured to the strain relief on the instrument bracket. Slide Mount Configurations include: i2, i1, iCon, S6, G12, G18, G12x, 9025, & 9025TR. G18 Slide Configuration

G18 VHMF

Vertical Hinged Mounting Frames (VHMF) enable the instrument chassis to be placed directly behind the VHMF. When using a VHMF, keep a space of 8-10" from the front of the chassis to prevent tight bends in the cables when the VHMF is closed. To determine the proper cable length required, measure the distance from the front face of the instrument to the module location in the receiver with the VHMF in the 'open' position, allowing for bends in the cable for proper cable routing and allowing extra length in the cable to prevent tight bends when the VHMF is closed.

Direct Panel Mount systems enable the instrument chassis to be placed directly behind the VPC receiver. When using the direct panel mount method, keep a space of 8-10" from the front of the chassis to prevent tight bends in the cable. To determine the proper cable length required, measure the distance from the front face of the instrument to the module location in the receiver, allowing for bends in the cable for proper cable routing. VHMF and Direct Panel Mount InterConnect options include: i1, iCon, iCon960, 2, 6, 10, 18, 25, 50, and 75 module solutions. G18 VHMF


With any configuration type, strain relief is critical in developing a reliable and consistent tester. VPC offers several strain relief options.

Module Strain Relief: The most common method is to attach strain relief plates directly to the modules. Wire or cable bundles are secured to the plate with wire ties, preventing forces exerted on the cables from transferring directly to the contact termination which can cause damage and loss of signal integrity.

Cable Tie Down Bar: A second method is to use cable tie-down bars on the receiver side. These bars are included with the Vertical Hinged Mounting Frames and are designed into the instrument bracket or cable tray kits used with slide-mount receivers.

When slide mounting your receiver, cables connecting to the receiver should be secured to the strain relief on the instrument bracket. This prevents the cables from being damaged when the slides are extended. Cables routed to instrumentation not placed on the instrument bracket should be secured to the strain relief on the instrument bracket.
