Test conditions as follows:
<p>

Microwave oven label says, in part: "GoldStar model 
GMS-7040TW.  Microwave power generator - Magnetron.  Operating 
frequency 2450 MHz.  Maximum output 700W, water-load 275 ml.  Normal 
operating voltage 4.0 Kv."  Oven operates on 120 VAC, 60 Hz, rated 
1000 Watts input, manufacturing date on label is "September 2005".
<p>

Measurement taken at 5 ft. horizontal range from closed oven door 
using 2.2 dBi vert. polarized omni antenna with estimated -0.2 dB 
adaptor connection loss.  Spectrum analyzer is Anritsu MS2721A, 
operated on internal battery (isolated from utility power to 
oven).  Noise floor was essentially flat around -80 dBm before start of test.
<p>

Test duration: 20 Sec. by oven timer (Max Hold was active).  Water 
load 250 ml. +/- 25 ml.  I didn't bother measuring field strength.
