P-326-1
Signal Generator
Description
P-326-1 product function
P-326-1 is classified as an Electrical signal generator. Its primary role is generation of a controlled electrical or radio-frequency signal. The complete designation, series and suffix letters form part of the identity and must not be shortened in an enquiry. This catalogue page supports product identification but does not replace the passport, illustrated parts catalogue or approved maintenance data for a particular aircraft installation.
The previously collected card data records the following: The measuring generator P-326-1 is a multifunctional source of sinusoidal electrical oscillations intended for use in measuring the parameters of communication lines, channels and paths of transmission systems with frequency division multiplexing during their adjustment, operation and repair. 1.

The basic error of setting the level of the output signal of the device measuring generator P-326-1 - no more than + 0.4 dB; 6. Uneven frequency response - no more than + 0.5dB; 7. Regulation of the output level of the device measuring generator P-326-1 - in steps of 1 dB; 0.1dB; 8. Protection of the output signal from non-harmonic components - not less than 60 dB; 9. Protection of the output signal from each of the harmonic components at levels of less than 10 dB at the outputs of 75 Ohm and 150 Ohm and at a level of 10 dB at the output of 600 Ohm - not less than 50 dB; 10. Attenuation of the output signal of the device measuring generator P-326-1 when blocking - not less than 50 dB; 11. Power consumed by the device from the 220V AC mains - no more than 120V ∙ A; 12. Weight of the device measuring generator P-326-1 - no more than 45 kg; 13. Overall dimensions - 500x480x260mm. These facts are retained for identification, but numerical values must be checked against the passport of the individual unit before use.

Role in the electrical system
An electrical machine or test source operates as part of a matched system. For a power unit, that system includes the mechanical drive, regulator, protection equipment, switching, wiring and connected loads. For a measuring generator, it includes the output circuit, load, monitoring equipment and approved test method. The general conversion principle is described in the electric generator reference. The exact P-326-1 connection must follow the documentation for the installed equipment.
A shared voltage or power rating does not establish interchangeability. Direction of rotation, speed range, drive flange, shaft, cooling, connectors, regulation, brush arrangement and permitted duty can differ. A starter-generator also requires verification in both operating modes, while an AC generator requires confirmation of frequency, phase configuration and the associated regulation and protection units.
Parameters and execution verification
Selection checks include the nameplate designation, series, technical specification, voltage, current or power, rotational speed, cooling method, direction of rotation and mass. This page retains only information already recorded in the Technical Details or confirmed for the exact designation. A missing parameter must be obtained from the offered unit passport rather than copied from a neighbouring family model.
A letter suffix or series number may identify a different construction, cooling arrangement, drive, rotation direction or electrical circuit. Hyphenated, compact and transliterated forms can be useful search variants, but they are not presented as separate interchangeable executions.
Installation and associated equipment
Before installation, inspect the mounting geometry, shaft and splines, fasteners, free rotation, collector or slip-ring condition, brushes, connectors, insulation and cooling passages as applicable. Regulators and protection units must be selected from the wiring data for the exact installation. Aircraft application is stated only when supported by documentation; visual similarity and a related designation are not sufficient evidence.
Related catalogue positions include M31305-5, SG-18-1S, GT60PCH8ATV, SGK-11/1.5KIS. These links provide navigation within the family and do not imply interchangeability. More electrical power units are listed in the Generators & Starter-Generators category.
Incoming inspection and maintenance
Incoming inspection should compare the marking and serial number with the supporting records and examine the housing, mounting points, terminals, connectors and seals. For a stored unit, confirm the last inspection date and the approved depreservation requirements. Electrical measurements, insulation testing, bench rotation and output checks must follow an approved procedure. Brush machines also require brush and collector assessment; brushless machines require attention to the exciter, rotating rectifier and bearings.
External appearance does not confirm serviceability. The required condition, inspection level, delivery set, passport and maintenance records should be agreed before installation. Release to service remains the responsibility of an authorized organization.
Identification and ordering of P-326-1
An enquiry should state the exact P-326-1 designation, series and execution, installed-system type, required condition and quantity. A clear nameplate photograph and the relevant parts-catalogue reference are useful. For replacement, also provide the drive, regulator and protection-unit designations and the network parameters. These details allow the configuration to be checked without assumptions and prevent confusion with a similarly named modification.
Price, actual availability, lead time, delivery scope and documentation are confirmed separately for the offered unit. State whether a passport, logbook, test report, preservation record, mating connector or mounting hardware is required.
