rohde: Universal Prüfsender - Power ON indicator and other items

Hello Gentlemen,

After posting the 5 pages of techical data for the BN4114 unit from Archives of the USA offices of R&S, I wish to identify one anomaly with the factory data presented to me.

The front plate of the Signal Generator of the production model which I have in my possession; and the same front panel of the unit from the late member Wesselin Tzenow,  depict the small Neon power ON indicator lamp (at the top center of the dial).

One additional item of concern relates to the technical data: since I have a copy of the Technical data folder 1148-87-b and the revised page "b" which pertains to the Output voltages values, there is no correlation to the "added" power ON neon lamp!!

Does any member have the technical data pages beyond page 4 of those sent to me from the USA office of Rohde & Schwarz?

I am preparing to begin the equipment checks to perform an alignment check on my early Argentin-produced Philips AL161 radio which has the IF requency of 175KHz. . . . .it appears as though the technical data states the IF wavelengths as being available from 330Khz up to 500Khz.

Am I seriously mistaken from the technical data??

Respectfully,

Robert

Dear Robert,

As far as I can see the first range is 100 - 340 kHz (green scale of the lower semi circle), which should cover the required 175 kHz.

The spread band is of course 330 to 500 kHz, a ratio of 1:1.5, while the first band has a little more than twice as much at 1:3.4.
Onthe other hand the relative bandwidth is much wider for low IF frequencies. That would already compensate a bit:

Range 2 has a span of 500-330= 170 kHz. 10 kHz are 1/17th of the scale (average).
Range 1 has a span of 340-100= 240 kHz. 10 kHz are 1/24th of the scale (average).
Not much of a difference in terms of frequency setting, isn't it?

I think at that time the lower IFs were outdated, in particular in Germany. That is my assumption, why range 2 was emphasised for the purpose of IF alignment.

Best regards,
KoBi
