Name
Description
1
Power input interface Instrument AC power input.
2
Slave USB interface The computer can perform remote control of the instrument through the slave
USB port.
3
Master USB
interface
It is connected to the USB program disk to update the instrument program.
4
Network port
The computer can perform remote control of the instrument through the network
port.
5
GPIB interface
The computer can perform remote control of the instrument through the GPIB
interface.
6
Trigger output
interface
The instrument is connected to a peak power sensor to measure the pulse
modulation signal and output the TTL level signal synchronized with the pulse
envelope.
7
Trigger
input
interface
The instrument is connected to a peak power sensor to measure the pulse
modulation signal. If the measured signal has a relatively small power and the
internal trigger signal is weak, trigger can't be achieved. At this time, the pulse
envelope signal synchronized with the measured signal can be connected to the
inside of the instrument via the trigger input interface. Through selection of
external trigger as the trigger source, the pulse envelope signal will be displayed
stably on the screen.
8
Rear panel input
option interface
The "Calibrator", "Channel A" and "Channel B" interfaces are reserved so that the
rear panel can be connected to a sensor for measurement to facilitate system
building.
9
Grounding terminal It facilitates common ground connection with other device.
2.3 Basic Measurement Methods
2.3.1 Description of basic operation
In this section, the methods for use of the S2438 series microwave power meter are generally introduced, including
information in the window display area and methods for use of the S2438 series microwave power meter through the
keys on the front panel and other interactive operations.
2.3.3.1 Value display information in case of connection with a peak power sensor
The measurement interface of the S2438 series microwave power meter connected to the peak power sensor is shown in
Fig. 2. 11. All information areas are marked and the operation interface is described in Table 2.7. A detailed introduction
is given hereinafter.
