B+K precision RFM3000 Series, User Manual, Page: 14 / 58

General Information 14
Item Description
1 USB Host
Four sensor inputs are located on the front and rear panels of the instrument. These are stan-
dard USB 2.0 Type A receptacles designed to accept only RFP3000 Series Sensors or standard
USB keyboards, mice, and flash drives.
2 Sync Ports
Four sensor trigger inputs are located on the front and rear panels of the instrument. These
are standard SMB receptacles designed to accept only BK Precision power sensor trigger ca-
bles.
Do not attempt to connect anything other than RFP3000
sensors and trigger cables!
3 RF Output
The output of the built-in 50 MHz programmable test source is available from a Type-N
connector located on the front, or optionally on the rear panel of the instrument. This test
source is used to verify basic performance of sensors used with the RFM3000.
4 Trig In
BNC input for connecting an external trigger signal to the power meter. Voltage range is
±
5
volts, but the input impedance is 1 Megohm to allow use of common 10x oscilloscope probe
for a
±
50 volt input range.
5 Multi-I/O
BNC input/output for flexible use. May serve as a status or alarm output, signal level moni-
tor, or settable voltage source
6 LAN Ethernet
LAN connector for remote control and firmware updates. Allows DHCP or fixed (IP / Sub-
net) setting mode. LAN parameters can be configured through the menu.
7 HDMI
HDMI receptacle for connecting an external monitor to mirror front panel display. The image
resolution will be 800 x 480 and will be stretched to fit the external full display size.
8 AC Line Input
A multi-function power input module is used to house the AC line input, main power switch,
and safety fuse. The module accepts a standard AC line cord, included with the power meter.
The power switch is used to shut off main instrument power. The safety fuse may also be ac-
cessed once the line cord is removed. The instrument’s power supply accepts 90 to 264 VAC,
so no line voltage selection switch is necessary.
Replace fuse only with specified type and rating:
1.0A-T (time delay type), 250 VAC.
9 HDMI Cooling air intake.
10 GPIB
24-pin GPIB (IEEE-488) connector for connecting the power meter to the remote control
General Purpose Instrument Bus. GPIB parameters can be configured through the menu.

1.6 Touch Screen Display
The RFM3000 can be controlled through the touch screen display and by use of the front panel buttons. Table 1.3
describes the different areas of the display layout of the RFM3000. Figure 1.3 shows the Graph Display mode of the
instrument using the Pulse Measure mode with a menu exposed. Figure 1.4 shows the same measure mode with the
