In order to protect the spectrum analyzer, the instrument test ports are provided
with some signs. To use the spectrum analyzer, be sure to read these signs to
avoid permanent damage to the instrument.
For details of the instrument signs, see section 3.2.4.
3.2.3 Digital interfaces
1) B-type USB interface: For connecting to the external PC. The PC uses the programmable commands or
programmable function library to achieve 4041 series program control or data transmission.
The first time you connect the spectrum analyzer to your PC via USB, you need to
install a device driver.
2) A-type USB interface: For connecting to the USB peripherals, such as USB storage devices, USB power
probes, etc.
3) LAN (network) port: This is a network port of 10/100 Mbps for connecting to the computer (PC) via network
cable. The PC uses the programmable commands or programmable function library to achieve 4041 series
program control or data transmission.
4) VGA interface: For connecting to the extern display device.
3.2.4 Instrument signs
The instrument signs (warning signs) indicate that the maximum input power of the test port is +30 dBm and the
maximum input DC level is 16 VDC. So the user must not connect signals beyond this range to the ports. Inputs
exceeding the above range may destroy the instrument!
