product appears electromagnetically "quiet", it is submitted to the
compliance certification laboratory. This should save the expense
for much of the test time, since the submitted unit has already been
pretested. Typically, the test time and money saved should represent
many times the purchase price of the spectrum analyzer.
Before performing measurements with two of the HZ530 probes,
the High Impedance (Hi-Z) Probe and the E-Field Probe they must
be configured for testing. The 0.8 mm diameter wires which are
used as antennas are located in the plastic bag that is in the case
for the probes. The wires are plugged into the probe by use of
pliers and a light force. The opening for the antenna is located on
the narrower front of the probes. The short wire is intended as a
contact for the Hi-Z probe.
E-field probe. Depending on the frequency range either the short
antenna (6.5cm) or the long antenna (9.5cm) is used.
Next, power must be provided to the probes. If a HM 5010 spec-
trum analyzer is used, the necessary voltage is obtained from the
HM 5010 by use of a provided special cable. In this case, batteries
are not required. If another spectrum analyzer, oscilloscope or RFI
measurement set is used for the measurement, the supply must
be provided via 4 AA-Cells either NiCad or rechargeable batteries.
Prior to each measurement the switch needs to be actuated. This
switch is located adjacent to the BNC connector. This switch must
be turned on when either the battery or spectrum analyzer supply
are used. However, when not in use, the switch must be turned
off to save the batteries which have a life of 20 - 30 hours when
turned on.
The connection of the probe to the spectrum analyzer, oscillosco-
pe or measurement receiver is made via a supplied BNC cable of
approximately 1.5 meters length. This length is generally sufficient
for most measurements. If for special reasons a longer cable is
