Fig. 3.34 Configuration of Multi-display Mode
➢
If [Monitor] is ticked, only the external VGA display to observe the measurement results, and the internal
LCD display of the analyzer will be ineffective.
➢
If [Built-in Display] is ticked, only the internal LCD display of the analyzer is used to observe the
measurement results, and the external VGA display will be ineffective.
➢
If [M Built-in Display] is ticked, the internal LCD display and external VGA display can be used as
the same time to observe the measurement results.
6) Lo Out and RF Out connector
As shown in Fig. 3.35 the 3.5mm female interface is used for LO output and RF output. The LO interface is used
for internal LO signal output, and RF interface for RF source signal output. The connector can be used for fault
detection and millimeter wave spreading. The interface features are as follows:
➢
Frequency range of LO output signal:
12.535MHz-13.507606GHz/26.507606GHz
➢
Power range of LO output signal: -4dBm to 6dBm
➢
Frequency range of RF output signal: 3.2GHz-13.5GHz/26.5GHz
➢
RF output signal power: -3dBm±2dB

7) Pulse I/O connector
As shown in Fig. 3.36, this is a 15-pin D-type female connector. The working state of the internal pulse generator
can be monitored synchronously through this interface. In addition,
Electrical features are as follows:
➢
Pulse width range: 33ns to 60s
➢
Pulse transition time: 30ns
➢
Input impedance: 1KOhm
➢
DC input:
＜
5.5V
➢
Drive voltage: 0V (off)+3.3V (on)
