Model 5344S
Operation and Programming
3-105.
Figure 3-6b
illustrates the 5344A rear panel features. The function of each control is
described as follows:
HP-18 Connector
Used to convey data and programming information. IEEE-1978 Compatible. See paragraph
3-138.
HP-IB ADDRESS Switches
The HP-IB address switch has seven individual switches, six of which are actually used. The
top switch determines if the 5344S's AUTO LOCK mode may be invoked from the front
panel. With the switch in the SYS CONT. position, the 5344S will act as an HP-IB system
controller to set sweeper parameters via HP-IB when AUTO LOCK is pressed. No other
system controller may be in a powered-up state on the bus if SYS CONT. is selected. When
the top switch is not in the SYS CONT. position, the 5344S may be programmed remotely
vai HP-IB by any bus controller.
The bottom five switches are used to set an HP-IB address in binary (bottom switch is the
LSB). HP-IB addresses must be in the range 0-30 (binary 0000 11110). If all of the address
switches are in the
"V
position, the 5344S will use address 30. If system controller mode is
selected (top switch in SYS CONT. position), the HP-IB address switches should be set to
the address of the sweeper to be controlled in AUTO LOCK. If system controller mode is
disabled, the HP-IB address switches determine the address by which the 5344S is accessed
on the bus by a remote controller. The unmarked switch is not used. Refer to paragraph
3-151. HP-IB Address Selection for more details.
FM OUT
This connector provides the frequency correction signal (FM) needed to maintain the
locked frequency output of the signal source. It must be connected to the FM input of the
signal source or locked operation.
SWP TRIG
This connector provides the signal necessary to control the sweeper in LOCK/ROLL
mode. It must be connected to the EXT TRIGGER connector on the sweeper (or,
optionally, STOP SWEEP on the 8350A).
IF IN
This connector must be connected to the IF OUT signal provided on the rear panel of the
5342A/43A.
10 MHz IN
This connector must be connected to the FREQ STD OUT (10 MHz) signal provided on the
rear panel of the 5342A/43A.
Input Power Module
AC input power module permits operation from 100-, 120-, 220-, 240- volts ac. The
number visible in the module window indicates nominal line voltage to which the
instrument must be connected (see
Figure 2-1).
The protective grounding conductor
connects to the instrument through this module.
