Section 3 Panel Description
3-5
No. Panel Marking Explanation of Function
17
Preset This sets the measurement parameters to the default values.
18 Local This changes the remote status to the local status.
19 Disp On/Off This sets the liquid crystal display On/Off.
20
Copy This outputs a hard copy of the screen to a printer or memory card.
21
Stby/On This is the power switch. It can be used when the back-panel power
switch is on. The power-on condition is fetched from the Stby condition
when the key is pressed for about 1 seconds. The equipment is returned
to the Stby condition from the power-on condition when the key is
pressed again for about 1 second.
22 RF Input This is the RF input connector.
23 I/Q Input
_
This is the I/Q Input connector. (Input I and Q for Unbalanced, and I/I
_
and Q/Q for Balanced.)
24 Probe Power This is the connector that supplies
±
12V for a FET probe.
Pin allocation is shown below.
GND No-connection
–12 V +12 V
25
Memory Card This is the slot to set memory cards which save/load the waveform data
and measurement parameters etc.
50 (Fan) This is the cooling fan for ventilating internally-generated heat. Leave a
clearance of at least 10 cm around the fan.
51 10 MHz STD They are the input connector for an external reference crystal oscillator
and the output connector of the 10 MHz Reference signal. When an
external reference signal is input, the equipment switches automatically
from the internal signal to the external signal.
If an external signal is input, the heater of the internal OCXO is switched
off.
52
IF Out put This is the IF output connector. This signal is bandwidth controlled by
the RBW setting.
