The TSG4100A Series RF Signal Generators provide waveform generation and
support both analog (standard) and vector/digital (optional) modulation. The
instruments use a new technique to provide spurious free outputs with low phase
se (-113 dBc/Hz at20 KHz offset from 1 GHz carrier) and extraordinary
noi
frequency resolution (1 μHz at any frequency). An ovenized SC-cut oscillator
(M00 or E1 optioned m odels) timebase provides 100 times improvement in
stability (and a 100 times reduction in the in-close phase noise) compared to
instruments that use a TCXO time-base. Key features include:

Clean the exterior surfaces of the chassis with a dry lint-free cloth or a soft-bristle
brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl alcohol
solution. Use a swab to clean narrow spaces around controls and connectors. Do
not use abrasive compounds on any part of the instrument because they might
damage the i
CAUTION. Avoid getting moisture inside the instrument during exterior cleaning;
use just enough moisture to dampen the cloth or swab. Do not wash the

Software upgrades are available from Tektronix. They can either be downloaded
from the Tektronix Web site or they can be ordered from your local Tektronix
representative. To add additional software options or features, you will need an
ption key from Tektronix. When you receive the software from Tektronix, you
o
will also receive an option key. Follow the instructions you receive to install the
software on your instrument. You will be prompted to enter the option key. See
the About menu on the instrument to enter an option key. This information is in
the Menus section of this manual. (See page 16 , Menus.)
If you return your instrument to Tektronix:
When repacking the instrument for shipment, use the original packaging. If
the packaging is unavailable or unfit for use, contact your local Tektronix
representative to obtain new packaging.
Seal the shipping carton with an industrial stapler or strapping tape.

AC power (input) Connect the unit to a power source through the power cord provided with the instrument.
The center pin is connected to the chassis so that the entire box is earth grounded. The
unit will operate with an AC input from 100 to 240 V
Hz. The instrument requires 85 W and implements power factor correction. Connect
only to a properly grounded outlet.
SYMBOL CLOCK
(output)
This BNC provides a square wave synchronized to the symbol clock used in the
modulation. The r ising edge of this clock triggers the programmed event markers
associated with the arbitrary waveform.
EVENT (outputs) Three BNC outputs labeled #1, #2, and #3 are available for synchronizing external
instrumentation to programmable events within a generated arbitrary waveform. These
may be programmed, for instance, to mark the start of a frame, or a slot within a frame,
or the start of a synchronizing pattern in the waveform. One of the event markers may be
further programmed to control the RF power of the front panel output for the generation
of TDMA signals. Events are triggered on the rising edge of the symbol clock.
VECTORMODINI
VECTOR MOD IN Q
These BNC inputs enable external I/Q modulation. They accept signals of ±0.5 V,
corresponding to full scale modulation, and have 50 Ω input impedances. Both inputs
support signal bandwidths from DC to 100 MHz providing an RF modulation bandwidth
of up to 200 MHz.
VECTOR MOD OUT I
VECTOR MOD OUT Q
These BNC outputs replicate the baseband I/Q modulation waveforms currently being
used to modulate the RF. Both outputs have a source impedance of 50 Ω and when
terminated into 50 Ω, will generate a full scale output of ±0.5 V.
ANALOG MOD OUT This output replicates the analog modulation waveform and has a 50 Ω reverse
termination. When using the internal source for AM, FM, and ΦM, it provides a waveform
determined by the function and rate settings with an amplitude of 1 V
impedance. During external analog modulation, this output mirrors the modulation
input. For Pulse modulation, the output is a 3.3 V logic waveform that coincides with
the gate signal.

ANALOG M OD IN External analog modulation is applied to this input. The input impedance is 100 kΩ with
a selectable input coupling of either DC or AC (4 Hz roll off). For analog modulations
(AM, FM, ΦM), a signal of ±1 V will produce a full scale modulation of the output (depth
for AM or deviation for FM and ΦM). It supports bandwidths of 100 kHz and introduces
distortions of less than –50 dB. For Pulse modulation types, this input is used as a
discriminator that has a fixed threshold of +1 V.

The instrument also provides a 10 MHz output for referencing other instrumentation
to the internal timebase.
This input accepts an external 10 MHz reference. The external reference should be
accurate to at least 2 ppm, and provide a signal of no less than 0.5 VPPwhile driving
a50Ω impedance. The instrument automatically detects the presence of an external
reference and locks to it, if possible. If the unit is able to lock to the reference, this is
indicated on the front panel display.
The Ethernet uses a standard R J-45 connector to connect to a local area network (LAN)
using standard Category-5 or Category-6 cable. It supports both 10 and 100 Base-T
Ethernet connection and a variety of TCP/IP configuration methods.
RS-232 The RS-232 port uses a standard 9 pin, female, subminiature-D connector. It is
configured as a DCE and supports baud rates from 4.8 kb/s to 115 kb/s. The remaining
communication parameters are fixed at 8 Data bits, 1 Stop bit, No Parity, with RTS/CTS
configured to support H ardware Flow Control.
GPIB The GPIB (IEEE-488) communications port is for communications over a GPIB bus. T he
instruments support the IEEE-488.1 (1978) interface standard. It also supports the
required common commands of the IEEE-488.2 (1987) standard.

external 10 MHz reference at the timebase input BNC. If detected, the instrument
will attempt to lock its internal clock to the external reference.
