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.

Fixed Rate Sweep: Allows the user to set the total time of the

sweep, including lock time. Variable from 20 ms to 99 seconds.

Switching Time (typical maximum): <15 ms + 1 ms/GHz step size

or <40 ms, whichever is less, to be within 1 kHz of final frequency.

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. User-selectable 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.

Switching Time (typical maximum): <25 ms to be within 1 kHz of

final frequency.

Sweep Triggering

Sweep triggering is provided for Analog Frequency Sweep, Step
Frequency Sweep, List Frequency Sweep, and CW Power Sweep.

Auto: Triggers sweep automatically.

External: Triggers a sweep on the low to high transition of

an external TTL signal. AUX I/O connector, rear panel.

Single: Triggers, aborts, and resets a single sweep. Reset sweep

may be selected to be at the top or bottom of the sweep.

General

Stored Setups: Stores front panel settings and nine additional front-

panel setups in a non-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 stored 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.

Parameter Entry: Instrument-controlled parameters can be entered

in three ways: keypad, rotary data knob, or the ^ and ∨ touch pads
of the cursor-control key. The keypad is used to enter new
parameter values; the rotary data knob and the cursor-control key
are used to edit existing parameter values. The ^ and ∨ touch pads
of 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 Anritsu ML2437A, ML2438A, and ML4803A and HP 437B,
438A, and 70100A. Five user tables are available with up to 801
points/table.

Warm Up Time:

From Standby: 30 minutes.
From Cold Start (0 deg C): 120 hours to achieve specified
frequency stability with aging.
Instruments disconnected from AC line power for more than
72 hours require 30 days to return to specified frequency stability
with aging.

Power: 85-264 Vac, 48-440 Hz, 250 VA maximum

Standby: With ac line power connected, unit is placed in standby

when front panel power switch is released from the OPERATE position.

User-Defined Modulation Waveform Software (Option 10)

An external software package provides the ability to download
user-defined waveforms into the internal LF Generator’s (Option

23) memory. The MG3690A provides as standard with the LF
Generator sinusoidal, square-wave, triangle, positive ramp,
Gaussian noise, and uniform noise waveforms.

IF Up-Conversion Application and Setup

IF 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 MG3690A, via three female
K-Connectors. The typical application will feed the MG3690A
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.

Mixer Type Double Balanced
RF, LO Range 1 to 40 GHz
IF Range DC to 700 MHz
Conversion Loss 10 dB Typical
Max Power into any Port 30 dBm
Isolation, RF to LO 23 dB
LO Drive Level (recommended) +10 to +13 dBm
Input P

+3 dBm Typical

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 IQ­modulated signal from an MG3681A, up-converting it to as high as
40 GHz with an MG3694A. A typical setup is shown below.

Frequency Range 2 to 18 GHz
Attenuation Range 0 to 60 dB
Flatness ±2 dB, 0 to 40 dB

±2 dB, 40 to 60 dB
Step Response < 1 ms
Sensitivity -10 dB/V
Insertion Loss < 6 dB (when engaged)
Input Rear Panel BNC connector

High Impedance

Scan Modulation (Option 20)

Option 20 adds a microwave linearly controlled alternator 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.

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.

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.

Millimeter Wave Multipliers (54000 Series plus Option 18)

External multipliers can be added to the MG3690A to provide
coverage as high as 110 GHz. Please call us for solutions beyond
110 GHz.

The 54000 series multipliers provide 50 to 75 GHz coverage in
WR15 or 75 to 110 GHz in WR10. An MG3690A with Option 18,
mmW bias, is required to drive these multipliers. The MG3692A
provides the input frequencies which are below 20 GHz. Higher
frequency MG3690A models could be used, but are not necessary.
Option 18 adds a rear panel BNC Twinax connector that supplies
the proper DC bias to power these external multipliers. (Option 18
is not available with Option 7.)

The 54000 series multipliers come in two versions, –4 and –5. Both
versions include input and output isolators for improved source
match. An external full-band “Through” (FL1) can be replaced with
either one of two split-band supplied external filters (FL2, FL3) for
better than –50 dBc spurious. The –5 version adds an internal
output coupler and a detector to supply a detected voltage output.
This output can be routed to the synthesizer’s external ALC input
for a flatter response, using External ALC Leveling mode.

Modulation can be used up to 110 GHz with these multipliers.
FM/ΦM’s deviation will be multiplied based on the multiplication
factor of the 54000 used. Pulse Modulation is available, with
sharper rise and fall times. AM is not recommended.
All performance is typical.
