7-2 2715 Spectrum Analyzer Service Manual

This is a no cost option that adds the IEEE Standard488 General Purpose

Interface Bus (GPIB). The pertinent circuitsare located on the Digital Option

board. The GPIB port consists of three compartments. They are the general

purpose interfacebus controller, an octal bus transceiver, and an eight channel

transceiver.In addition, there is circuitry included to drive two LEDs to display

the status of the Not Ready For Dat a (NRFD) and Not Data Accepted (NDAC)

handshake lines.

The general purpose interfacebus controller, octal bus transceiver, and eight

channel transceivermeet the IEEE-488 1975/78 standards along with the

IEEE-488A1980 supplement.

For programming, see the 2714 & 2715 Programmer Manual.

The rear panel connection providesfull GP IB printercompatibility.

If this option is specified, Option 08 is not available.

This option adds the 2707 External TrackingGenerator (Option 01). In addition,

Option 15 (1st LO output) is included to provide the drivesignal for the 2707.

This option comprises the Tektronix2704 DC Inverter and 2705 Battery Pack.

The Inverter and Battery Pack are designed to all ow operation of the Spectrum

Analyzer in locations where AC power i s not available.

The Inverter and Battery Pack combinati on is capable of operating the Spectrum

Analyzer for a minimum of one hour.Moreover, the Inverter contains a charger

and an 18 VDC output to power external devicessuch as Low Noise Block

(LNB) Down Converters used in satellitedown link applications. The Inverter

also includes an additional 12 V input to allow useof external batteries without

power interruption to the Spectru m Analyzer.T he Inverter and Battery Pack

form a matching unit and attach together to t he Spectrum Analyzer. At least one

Battery Pack is needed with each inverter for no rmal operation and to add

stability when mounted to the Spectrum Analyzer.

Referto the 2074 Inverter and 2705 Battery Pack Instruction Manual for

specifications, installation instructionsand other pertinent information.

This option adds the RS-232 Interface port, a no cost option. The pertinent

circuits are locatedon the RS-232 board. If this option is specified, Option 03 is

not available.

This option provides an interfacefor the 1405 TV Sideband Analyzer and the

Option 05 External TrackingGenerator. The 1st LO is routed from J300 on the

1st LO Buffer Amplifierassembly to J101 at the rear panel and terminated in

50 Ω. See Figure 7--1.
