To inspect package contents

❏Inspect the shipping container for damage.

If your shipping container appears to be damaged, keep the shipping container or cushioning material until you have inspected the contents of the shipment for completeness and have checked the oscilloscope mechanically and electrically.

❏Verify that you received the following items and any optional accessories in the oscilloscope packaging (see figure following).

•54620-Series Oscilloscope (54621A, 21D, 22A, 22D, or 24A)

•10074C 10:1 150 MHz passive probes with ID:

(2)for 54621A, 21D, 22A, or 22D oscilloscopes

(4)for 54624A oscilloscope

•54620-68701 digital probe kit (for 54621D or 22D)

•Accessory pouch and front-panel cover (standard for 54622A, 22D, and 24A) (optional on 54621A and 21D; order N2726A)

•Power cord (see table 1-3)

•IntuiLink for 54600-series Oscilloscopes software and RS-232 cable (for 54622A, 22D, or 24A).

IntuiLink is a Windows application that makes it very easy for you to download images, waveform data, or oscilloscope setups from the oscilloscope to your pc using either Microsoft Word or Microsoft Excel. After installation of IntuiLink, a tool bar in these Microsoft applications will make connection and data transfer from the oscilloscope very simple.

IntuiLink software is available free on the web at: www.agilent.com/find/5462xsw

RS-232 cable may be ordered separately, part number 34398A

If anything is missing, contact your nearest Agilent Sales Office. If the shipment was damaged, contact the carrier, then contact the nearest Agilent Sales Office.
