EM-2115 3.0 PERFORMANCE CHECK
(EM2115S3-5)
1)
Change the Impulse Generator output amplitude level to +60 dB(µV/MHz).
2)
Set the BANDWIDTH to 1 MHz.
3)
The Broadband Correction Factor plus meter indication should equal +60
dB(µV/MHz) ±2.0 dB.
3.4.3 Frequency Accuracy
Specification: ±0.1% ±1 count ±0.2 resolution BW
Equipment required: Signal Generator
This test procedure is performed at three test frequencies per
frequency range selected using the method described in para-
graph 3.3.3.
a.
Set the front panel controls as follows:
DETECTOR ...................................................AVERAGE
SAMPLE TIME Control ................................Mid-range.
BANDWIDTH ...............................................Narrowest position of the frequency
range selected.
ATTENUATION ...........................................40 dB
FREQUENCY RANGE .................................0.009-0.035 MHz.
b.
Perform the calibration sequence described in 3.4.1 Step b.
c.
Apply a CW signal at the test frequency selected to the RF Input of the EM-2115.
Set the signal input level at +40 dB(µV)(100 µV).
d.
Peak the signal source for a maximum indication on the front panel analog meter
(use the method described in Paragraph 3.3.4).
e.
The frequency indication of the receiver should be within ±0.1% ±1 count ±0.2
resolution BW of the signal source frequency.
f.
Repeat Steps b thru d for Frequency Ranges 1-10 (0.009-30 MHz) at each of the
three frequency test points selected.
g.
Repeat Steps b thru e for Frequency Ranges 11-15 (30-1000 MHz) at each of the
frequency test points selected. Set the CW input level at +60 dB(µV)(1 mV).
3.4.4 Attenuation Accuracy
Specification: ±1.0 dB
