Options 4 and 5: Frequency extension down to 10 MHz
Two options are available to extend the 2 GHz low end frequency limit of the base
models down to 10 MHz. Option 4 uses a digital down-converter (DDC) with successive
divide-by-two circuitry. It offers the best phase noise performance of the two choices, at
the expense of some analog performance <500 MHz. In that range, analog sweep mode
is not available, and pulse modulation performance is specified as typical. In addition,
frequency and phase modulation mod index is scaled by the division ratio of each band
of the DDC. Option 5 maintains all analog performance by using a heterodyne mixing
down-converter
.
Option 22: Frequency extension down to DC
If frequency coverage down to 0.1 Hz is desired, Option 22 can be added with either
Option 4 or 5. Option 22 uses Direct Digital Synthesis (DDS) for CW and Step Sweep
modes of operation. Modulation and analog sweep are not available in the DDS band.
Frequency resolution <10 MHz is 0.02 Hz. Output power across the complete instrument
frequency range is degraded by 2 dB.
Accuracy: Same as internal or external 10 MHz time base.
Resolution (Minimum Step Size): 0.01 Hz
Independently selected, 0.01 Hz to full range. Every frequency step in
Linear/Log Sweep: User-selectable linear or log sweep.
I
n log sweep, step size logarithmically increases with frequency.
Steps: User-selectable number of steps or the step size.
Number of Steps: Variable from 1 to 10,000
Step Size: 0.01 Hz to the full frequency range of the instrument.
(If the step size does not divide into the selected frequency range,
the last step is truncated.)
Dwell Time Per Step: Variable from 1 ms to 99 seconds
Fixed Rate Sweep: Allows the user to set the total time of the sweep,
including lock time. Variable from 20 ms to 99 seconds.
Analog Sweep Mode (Option 6)
Sweep Width: Independently selected from 1 MHz to full frequency range. With Option
4, Digital Down Converter, Analog sweep is only available ≥500 MHz. Analog sweep is
not available <10 MHz with Option 22.
Accuracy: The lesser of ±30 MHz or (±2 MHz + 0.25% of sweep width)
for Sweep Speeds of
≤50 MHz/ms (typical)
Sweep Time Range: 30 ms to 99 seconds
Alternate Sweep Mode
Sweeps alternately in step sweep between any two sweep ranges. Each sweep range
may be associated with a power level.
Manual Sweep Mode
Provides stepped, phase-locked adjustment of frequency between sweep limits. Userselectable number of steps or step size.
List Sweep Mode
Under GPIB control or via the front panel, up to 4 tables with 2000 non-sequential
frequency/power sets can be stored and then addressed as a phase-locked step sweep.
One table of 2000 points is stored in non-volatile memory, all other tables are stored in
volatile memory
.
Programmable Frequency Agility
Under GPIB control, up to 3202 non-sequential frequency/power sets can be stored and
then addressed as a phase-locked step sweep. Data stored in volatile memory.
Markers
Up to 20 independent, settable markers (F0 – F9 and M0 – M9).
Video Markers: +5V or –5V marker output, selectable from system menus. AUX I/O
connector, rear panel.
Intensity Markers: Produces an intensity dot on analog display traces, obtained by a
momentary dwell in RF sweep, in analog sweeps of <1s.

Stored Setups: Stores front panel settings and nine additional front-panel setups in a
n
on-volatile RAM. A system menu allows saving and recalling of instrument setups.
Whenever the instrument is turned on, control settings come on at the same functions
and values existing when the instrument was turned off.
Memory Sequencing Input: Accepts a TTL low-level signal to sequence through ten
s
tored setups. AUX I/O connector, rear panel.
Self-Test: Instrument self-test is performed when Self-Test soft-key is selected. If an
error is detected, an error message is displayed in a window on the LCD identifying the
probable cause and remedy.
Secure Mode: Disables all frequency and power level state displays. Stored setups
saved in secure mode remain secured when recalled. Mode selectable from a system
menu and via GPIB.
P
arameter Entry:Instrument-controlled parameters can be entered in three ways:
keypad, rotary data knob, or the
keypad is used to enter new parameter values; the rotary data knob and the cursorcontrol key are used to edit existing parameter values. The
cursor-control key move the cursor left and right one digit under the open parameter.
The rotary data knob or the ∧ and ∨ touch pads will increment or decrement the digit
position over the cursor. Controlled parameters are frequency, power level, sweep time,
dwell time, and number of steps. Keypad entries are terminated by pressing the
appropriate soft key. Edits are terminated by exiting the edit menu.
Reset: Returns all instrument parameters to predefined default states or values.
Any pending GPIB I/O is aborted. Selectable from the system menu.
Master/Slave Operation: Allows two output signals to be swept with a user-selected
frequency offset. One instrument controls the other via AUX I/O and SERIAL I/O
connections. Requires a Master/Slave Interface Cable Set (Part No. ND36329).
User Level Flatness Correction: Allows user to calibrate out path loss due to external
switching and cables via entered power table from a GPIB power meter or calculated
data. When user level correction is activated, entered power levels are delivered at the
point where calibration was performed. Supported power meters are
ML2438A, and ML4803A and HP 437B, 438A, and 70100A. Five user tables are
available with up to 801 points/table.

Amplitude Modulation (Option 14)
O
ption 14 adds amplitude modulation, driven externally via a rear panel BNC
connector 50

All amplitude modulation specifications apply at 50% depth, 1 kHz rate, with RF level set
6 dB below maximum specified leveled output power, unless otherwise noted. Amplitude
M
odulation is not available <10 MHz with Option 22.
An internal pulse generator and two internal waveform generators are added, one
p
roviding a frequency or phase modulating signal and the other an amplitude modulating
signal. This Internal LF and Pulse Generators option can only be ordered in combination
with either FM/
ΦM, AM, or Pulse options, 12, 14, and 26 respectively.

F Up-Conversion (Option 7)

Option 7 adds an internal mixer that can be used for the generic up-conversion of
an IF signal. The mixer’s RF, LO, and IF ports are made available at the rear panel
of the MG3690B, via three female K-Connectors. The typical application will feed the
MG3690B microwave output, which can be moved to the rear panel via option 9K,
to the mixer’s LO port. An external IF signal will be fed to the mixer’s IF port. The
new up-converted signal will be available at the mixer’s RF port.

The IF Up-Conversion option is particularly useful to create a microwave frequency
IQ-modulated signal. Lower frequency IQ-modulated RF sources are readily
available, such as the Anritsu MG3681A. Option 7’s IF input can be used to feed in
an IQ-modulated signal from an MG3681A, up-converting it to as high as 40 GHz
with an MG3694B. A typical setup is shown below.
An external software package provides the ability to download user-defined
waveforms into the internal LF Generator’s (Option 27) memory. The MG3690B
provides as standard with the LF Generator sinusoidal, square-wave, triangle,
positive ramp, Gaussian noise, and uniform noise waveforms.
Two look-up tables of 65,536 points can be used to generate two pseudo-random
waveforms, one for amplitude modulation and the other for frequency or phase
modulation. The download files are simple space-delimited text files containing
integer numbers between 0 and 4095, where 0 corresponds to the minimum
modulation level and 4095 the maximum.
In addition to the capability of downloading custom waveforms, the software offers
a virtual instrument modulation panel. Custom modulation setups with user
waveforms can be stored for future use. For IFF signal simulation, the internal
generators can be synchronized. They can also be disconnected from the internal
modulators, making the low frequency waveforms available at the rear panel for
external purposes.
can Modulation (Option 20)
S
Option 20 adds a microwave linearly controlled attenuator to provide deep AM
capability. This modulator is inserted outside the leveling loop but before the
optional step alternator. It is switched in and out of the RF path. Scan modulation
is driven externally only.
One application of this feature is storing an antenna pattern wave form in memory
and using it to feed the external input to the scan modulator, Option 20.

mmW Frequency Coverage
Millimeter Wave Multipliers1 - 63850 series
(Option 18 recommended for DC bias.)
6
3850 series external, waveguide output, multipliers are available for banded frequency
coverage up to 325 GHz.
These external multipliers require at a minimum an MG3692B, with 20 GHz coverage.
The output power required to drive the modules is +10 dBm. They can be powered up
b
y an external power supply (+12Vdc, 1.5A typ.) using the supplied double banana
power cord. It is recommended to purchase an MG3690B with option 18, which adds the
capability to bias these modules without the need of an additional power supply. It adds
a rear panel Twinax connector that supplies the proper DC bias for these modules, and a
cable to power them up. Option 18 is not available with options 7 and 15.
63850 series multipliers have a saturated, unleveled, output power, yet their inherent
flatness is exceptional. Modulating the input drive will indeed modulate the output,
except for the case of Amplitude Modulation. Since the output is saturated, Amplitude
Modulation is not recommended with these mmW modules. Frequency and Phase
Modulation is possible, but the achieved deviation will be multiplied based on the
multiplication factor of the module. Pulse modulation is also possible, with even sharper
rise and fall times than the input. All modulation performances are not specified.
For ease of operation, the MG3690B allows the user to enter a frequency scaling factor,
the module's multiplication factor, which will be used only for purposes of displaying the
proper frequency at the output of the mmW module, on the MG3690B's front panel display.
