2.4.6 Connecting the Converter to the DC Supply
An external DC power supply and several plug adapters are provided with the instru-
ment. Select the appropriate adapter and attach it to the power supply. To remove a
mounted adapter press the small button next to the adapter and push the adapter
away from the button.
Connect the power supply to the "9 V / MAX. 1.1 A" DC input on the rear panel (see
chapter 2.3.2, "Power Supply Connector"
,
on page 9) and to a power outlet. The power
supply supports input AC voltages between 100 V and 240 V and frequencies between
47 Hz and 63 Hz.
A lit LED next to the standby switch indicates that the power supply operates appropri-
ately. If neither of the two LEDs is lit, check the fuse of the instrument (see
chap-
ter 2.4.9, "Replacing Fuses"
,
on page 16).

ZVA-Z500 converters
The external DC power supply units of R&S
ZVA-Z500 converters support higher out-
put powers; the DC input connector at the rear panel is labeled "9 V / MAX 1.6 A".
Always use the DC power supply delivered with your frequency converter.
2.4.7 Switching on the Instrument
The standby toggle switch is located at the rear panel (see
chapter 2.3.1, "Standby
Switch"
,
on page 8). To switch the instrument to ready state, press the key. The green
LED next to the switch must be lit now.
After switching the instrument to the ready state a warm-up time of one hour is
required to ensure accurate measurements. The instrument is only warmed-up in
ready state, not in standby state.
