EM-2115 3.0 PERFORMANCE CHECK
(EM2115S3-4)
d.
Peak the signal for a maximum indication on the front panel analog meter (use the
method described in Paragraph 3.3.4). Verify that the digital meter reads +40
dB(µV) ±2.0 dB.
e.
Repeat Steps b thru d for Frequency Ranges 1-10 (0.009-30 MHz) for each of the
three frequency test points selected.
f.
Repeat Steps b thru d for Frequency Ranges 11-15 (20-1000 MHz) for each of the
three frequency test points selected. Set the CW signal at an input level of +60
dB(µV), the digital meter should in60 dB(µV) ±2.0 dB.
3.4.2 Broadband Voltage Accuracy
Specification: ±2.0 dB
Equipment required: Impulse Generator (EM-4320)
a.
Set the front panel controls as follows:
DETECTOR ...................................................PEAK.
SAMPLE TIME Control ................................Mid-range.
BANDWIDTH ...............................................9/10 kHz.
ATTENUATION ...........................................40 dB.
FREQUENCY RANGE (Initial) ....................0.009-0.035 MHz.
FREQUENCY INDICATION (Initial) ..........0.022 MHz. Midrange frequency
point of Frequency Range 1.
b.
Perform the calibration sequence described in 3.4.1 Step b.
c.
Connect the output of an Impulse Generator to the front panel RF Input Connector
and set the output amplitude level at 80 dB(µV/MHz).
d.
Add the Broadband Correction Factor from the broadband correction chart for the
frequency range being used to the digital meter indication. For Frequency Range 1
(0.009-0.035 MHz), the broadband correction factor is nom40 dB. The re-
sults should be the broadband level +80 dB(µV/MHz) ±2.0 dB.
e.
Repeat Steps b thru d for Frequency Ranges 2-7 (0.035-2.4 MHz).
f.
Repeat Steps b thru d for Frequency Ranges 8-10 (2.4-30 MHz) except for the fol-
lowing:
1)
Set the BANDWIDTH to 100/120 kHz.
2)
The Broadband Correction Factor plus meter indication should equal +80
dB(µV/MHz) ±2.0 dB.
g.
Repeat Steps b thru d for Frequency Ranges 11-15 (25-1000 MHz) except for the
following:
