I have assembled three different kits for this OCXO design which is compatible with both the HP5315A and HP5316A. Everything is through-hole and assembly can be completed in 15-20 minutes. At this time I have the kits on my website @: https://www.hollywoodcontrols.com/phpHP/HP004OK.php Where you can get the kit with or without the MV85 oven oscillator or just the single PCB. If you prefer eBay you can get the same thing at: https://www.ebay.com/itm/155741314023 But eBay takes about 25-30% of sellers price which includes listing price, shipping and sales tax. So the prices are higher. |

Anybody know if the HP5316A/B uses reciprocal counting for the lower frequencies? so measurements are fast and accurate even in the low Hz range. If not, is there a similar HP model that does use reciprocal counting? Thank you. |

Thank you. --- End quote --- According to 3-4 of the 5316A operating manual: "To maximize resolution, the 5316A uses a reciprocal counting technique for frequencies below 10 MHz, automatically switching to conventional frequency counting for frequencies above 10 MHz." |

Its a pain having to wait 10 seconds before getting a low Hz reading with my current counter, specially when trying to make fine adjustments to a 60Hz oscillator. |
