[Milsurplus] Sweep range for Re: HP8601A Crystal filter adjustment

[John Hutchins]

Hue -

I think that a Symmetrical sweep of +/-10kHz is low enough to get what I 
need?

HP8601A
Symmetrical sweep above and below selected front panel frequency setting 
from .01Mhz to 1.0 Mhz sweep for low band of 0.1 Mhz to 11 Mhz ; and 
from 0.1 Mhz to 10Mhz sweep on high band of 1.0Mhz to 110 Mhz .  A sweep 
vernier adjusts the sweep width from 0 to a calibrated position.

2 units are complete not calibrated.
1 unit needs a power switch button, otherwise complete.
1 unit much older needs a replacement of power connector, has old round 
3 prong type power cable, will change out male AC socket to use the 
standard Computer type power cord. The unit is also missing a small 
plastic finger hold on band "slider/throw" switch.

Problem 1:
All the out put meters rest at "Zero" left marking with power off so 
meters are mechanically sound.  When a unit is powered up and output 
vernier is cranked CCW all Left needle does not rest at far left mark 
"Zero" -? DB on meter, with Zero RF volts measured at output.

Plan to first check the reg. power supply voltage of  20V.  Check the 
oil ;-} Then send off to get calibrated.

Chuck a member of the hp_agilent_equipment at yahoogroups.com has given me 
a heads up on what to look for on the meter adjustment.  

Down loaded the manual from BAMA  thanks to responses from members of  
milsurplus at mailman.qth.net hp_agilent_equipment at yahoogroups.com groups.

May Thanks all-
Hutch
