GPIB address

Selectable from a system menu

IEEE-488 interface function subset

SH1, AH1, T6, L4, SR1, RL1, PP1, DC1, DT1, C0, C1, C2, C3, C28, E2

The instrument responds to the published GPIB commands and responses of the models 6XX00-series

Emulations

signal sources. When emulating another signal source, the instrument is limited to the capabilities,
mnemonics, and parameter resolutions of the emulated instrument.

Stores front panel settings and nine additional front-panel setups in a non-volatile RAM. A system menu

Stored setups

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 nine 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.

Secure mode

Disables all frequency, power level, and modulation state displays. Stored setups saved in secure mode
remain secured when recalled. Mode selectable from a system menu and GPIB

Reset

Returns instrument parameters to predefined default states or values. Any pending GPIB I/O is aborted.
Selectable from the system menu

Allows two 68X00B output signals to be swept with a user-selected frequency offset. One 68X00B unit

Master/slave operation

controls the other via AUX I/O and SERIAL I/O connections. Requires MASTER/SAVE interface cable set

(part no. ND36329)

Allows user to calibrate out path loss due to external switching and cables via entered power table from a

User level flatness correction

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 ML4803A
and HP437B, 438A, and 70100A. Five user tables are available at up to 801 points/table

*

1: All specifications apply to the phase-locked CW and step sweep modes at the lesser of +10 dBm output or maximum specified levelled output power, unless

otherwise noted.

*

2: >40 GHz units and units with Option 15 at maximum specified levelled output power

*

3: For 6x1x5 units, maximum sensitivity is divided by 2 from 1 to 2.2 GHz and is divided by 4 from 500 MHz to 1 GHz.

*

4: The RF output can be pulse modulated via an external modulating signal or an internal square wave generator

*

5: All amplitude modulation specifications apply at 50% depth, 1 kHz rate, with RF level set 6 dB below maximum specified levelled output power, unless oth-

er-wise noted

*

6: All pulse modulation specifications apply at maximum specified levelled output power, unless otherwise noted

*

7: Maximum attenuation = attenuation ±flatness

*

8: 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).
