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.
Weight: 18 kg maximum
Dimensions: 133 H x 429 W x 450 D mm
Warranty: 3 years from ship date
Remote Operation
All instrument functions, settings, and operating modes (except for
power on/standby) are controllable using commands sent from an
external computer via the GPIB (IEEE-488 interface bus).
GPIB Address: Selectable from a system menu
IEEE-488 Interface Function Subset:
Source Handshake: SH1
Acceptor Handshake: AH1
Talker: T6
Listener: L4
Service Request: SR1
Remote/Local: RL1
Parallel Poll: PP1
Device Clear: DC1
Device Trigger: DT1
Controller Capability: C0, C1, C2, C3, C28
Tri-State Driver: E2
GPIB Status Annunciators: When the instrument is operating in
Remote, the GPIB status annunciators (listed below) will appear in a
window on the front panel LCD.
Remote: Operating on the GPIB (all instrument front panel keys
except for the SYSTEM key and the RETURN TO LOCAL soft-key
will be ignored).
LLO (Local Lockout): Disables the RETURN TO LOCAL soft-key.
Instrument can be placed in local mode only via GPIB or by cycling
line power.
Emulations: The instrument responds to the published GPIB
commands and responses of the Anritsu Models 6600, 6700,
and 6XX00-series signal sources. When emulating another
signal source, the instrument will be limited to the capabilities,
mnemonics, and parameter resolutions of the emulated instrument.
