By default the R&S®HMO3000 series is equipped with a
dual interface Ethernet/USB (HO730). The following optio-
nal interface modules are available and may be installed by
the customer in the rear receptacle:
❙ HO720 (combination of USB and RS-232)
❙ HO732 (combination of Ethernet and USB with integrated
web server)
❙ HO740 (IEEE-488, GPIB, galvanically isolated)
All instruments of the R&S®HMO3000 series are prepared
for mixed-signal operation and have the appropriate con-
nectors on the front panel. Each of these connectors can
be connected to an 8-channel logic probe R&S®HO3508,
allowing a maximum of 16 digital logic channels. Further
options are the passive 1000:1 probes with up to
4000 V of the type HZO20, active 10:1 probes with

2.8 Self Alignment
The R&S®HMO3000 series features an integrated self
alignment procedure to achieve the highest possible ac-
curacy. During the standard self alignment the instrument

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.

internally. 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.
2.8.1 Logic Probe Self Alignment
The self alignment for the optional logic probe
R&S®HO3508 primarily aligns the switching levels. To start
the self alignment for the logic probe, it is necessary that
the logic probe type R&S®HO3508 is connected to the
R&S®HMO3000 series. It is imperative that the bit connec-
tors are not connected. To start the process, select the
menu item LOGIC PROBE in the SELF ALIGNMENT soft
menu. The process is similar to the basic instrument align-
ment but it only takes a few seconds.

If an error occurs during the self alignment although it has been
carried out as described, please send the exported .log le (see
