Introduction

Once you have entered the voucher code on the

homepage http://voucher.hameg.com, the licence key will

begenerated(„SERIALNUMBER.hlk“).TheASCIIlemay

be opened with an editor. This allows you to read the

actual key in plain text. You can choose between two

methods to enable the desired option with this key: an

By default the R&S®HMO Compact series is equipped with

a dual interface USB/RS-232 (HO720). The following optio-

nal interface modules are available and may be installed by

the customer in the rear receptacle:

❙ HO730/HO732 (combination of Ethernet and USB with

integrated web server)

❙ HO740 (IEEE-488, GPIB, galvanically isolated)

All instruments of the R&S®HMO Compact series are pre-

pared for mixed-signal operation and have the appropri-

ate connectors on the front panel. Connecting an 8-chan-

nel logic probe R&S®HO3508 equips the scope with 8 logic

channels. Further options are the passive 500 MHz

10:1 probes of the type RT-ZP05, passive 1000:1 pro-

bes with up to 4000 V of the type HZO20, active 10:1 pro-

bes with

tial probes HZO40 and HZO41 with 200 or 800 MHz band-

width, the current probes HZO50 and HZO51 with up to

100 kHz bandwidth and up to 1000 A, the 19“ rack-mount

set HZO91 and the type HZO90 transport bag for the pro-

tection of the instruments.

2.8 Self Alignment

The R&S®HMO Compact series features an integrated self

alignment procedure to achieve the highest possible accu-

racy. During the standard self alignment the instrument ad-

justs vertical accuracy, offset, time base and several trig-

gersettingsandsavestheidentiedcorrectiondatainter-

nally. To start the self alignment in the SETUP menu, press

the soft menu key SELF ALIGNMENT and press the START

key. The procedure will run for about 5-10 minutes. Each

step and its corresponding progress will be shown in a bar

display.

The instrument must have reached the required operating tempe-

rature (switched on for at least 20 minutes) and all inputs must

be unused, in other words all cables and probes must be removed

from the inputs.
