Figure 6 – The SeeSii JDS6600 rear panel.
SeeSii JDS6600-60M
The documentation for the two models is slightly differ-
ent. The JDS2900 comes with both a mini CD and a
small quick-start booklet, and the JDS6600 comes with
a larger instruction summary book. The CDs are similar,
and the company name (Hangzhou Junce Instruments
Co., Ltd.) is the same. Because the same Quick Guide
apparently holds for both models, the manufacturer’s
host name on both PDF les holds for both JUNTEK and
SeeSii — not an unusual situation for an electronic de-
vice imported from the Far East. While the units appear
to be electrically similar, notice the price difference.
Manufacturer: SeeSii. Price: $139.99. Available at

If you have ever searched online for an item from a
conglomerate supplier such as Amazon, you have prob-
ably found a web page that hosts several similar items,
from which you have to pick one. In order to compare
two similar signal generators, I selected the JDS2900
(reviewed earlier) and the JDS6600.
Their similarities become obvious when you notice that
the Quick Guide supplied with the JDS2900 does not
list the several models of the JDS2900, but lists the
models of the JDS6600. The JDS2900 comes from a
company called JUNTEK, and the JDS6600 comes
from a company called SeeSii.
There is a mechanical difference between the two.
The SeeSii lead photo shows the front panel of the
JDS6600. The layout is different from the JDS2900, but
the controls are similar. The biggest difference is the
size; the JDS2900 is approximately 4 × 1.5 × 4 inches,
while the JDS6600 is approximately 7.6 × 2.7 × 7 inches.
The location of the connectors is also different. The
JDS2900 has connectors on both sides. The JDS6600
has two channel outputs and the measurement port on
the front panel, and the dc connector, a USB type B
port, and a
TTL connector on the rear (see Figure 6).
The
TTL connector on the JDS6600 is a rectangular
10-pin polarized male, while the JDS2900 uses a BNC
connector.
The front panel of this industrial-strength waveform
generator is labeled “Easy Pulse,” and many of its func-
tions are easy to set up, customize, and use. There are
other capabilities for which you may need the online
documentation. This 9 × 4 × 11.5-inch unit, including
corner bumpers (but not including the handle), weighs
slightly less than 10 pounds. It is capable of generating
two separate outputs, but it displays the output settings
and waveform pictures of only one channel at a time.
The unit reviewed here is a 30 MHz model. It comes
with a calibration certi cate and calibration traceability,
meeting several industry and government requirements
and speci cations. The shipping carton contains the
main unit, a power cord, and a USB jumper.

on the buttons (except for programming custom wave-
