In the lower right corner, a third BNC connector feeds
an internal frequency counter. The counter is selected
by a button just above and to the right of this BNC, and
is listed as capable of measuring frequencies to
200 MHz with a seven-digit display.
Rear Panel Connections —
Input, Output, and Control
On the rear panel (see Figure 8), there are three BNC
connectors that have multiple uses, depending on how
the generator is being used. The legend shown above
each connector is a summary of the use of that connec-
tor. When channel 1 is selected on the front panel, the
rst (leftmost) connector puts out a corresponding sync
signal. If channel 2 is selected, the second BNC puts
out a corresponding sync signal.
The rst BNC connector has several other uses. It
accepts an external modulation signal, control of an
FSK signal again if selected, and a port for trigger in
and out. The second BNC connector has a similar set
of uses when channel 2 is selected for output.
The third BNC connector, when con gured, puts out the
internal 10 MHz clock source or alternately accepts
input from an external 10 MHz source. The next con-
nector is a standard Ethernet LAN socket allowing the
generator to be used and controlled as part of a com-
plete test setup, meeting an industrial standard called
out in the user’s guide.
A standard USB connector completes the set. It can be
used to control the generator externally from a PC. It
can also be connected to a PictBridge printer (an indus-
try standard) to print the contents of the screen. Finally,
on the right is an ac power socket.
In Summary
Both the LAN and the USB connectors provide ports
that can be used to con gure and control the generator.

In the January 2023 issue of QST, Figure 2 in “Antenna
Switch for Three Remote Operating Locations” in the “Hints
& Hacks” column contains two incorrect connections. The
Relay 2 connection to the yellow wire should be made to
the green wire, and the junction of the S2 and LED4 con-
nection to the yellow wire should also be made to the green
wire. A corrected schematic has been added to the QST in
Depth web page at www.arrl.org/qst-in-depth.
In the February 2023 “Product Review,” two errors were
made that have since been corrected in the digital edition.
First, the placement of Figures B and C should be reversed.
Please note that this refers to the images only; the captions
are in the correct places. Second, in the caption for Figure
C, the second sentence should read, “Third-order products
are –28 dB
PEP
, and fth-order products are –39 dB
PEP
.”
QST regrets these errors.
