Peak Hold – This will keep the last trace draw on the screen. This is valuable for measuring quick transmissions over time.
Trace Det – Trace detection
Trace Avg – Trace averaging
RBW – Resolution Bandwidth
Marker – The marker is a visual reference tool for analyzing points on the screen. When the marker check box is set, clicking on
the screen will place a yellow diamond marker (Figure 12) that can be moved to any point on the screen. The frequency and signal
level at the marker location will be shown in the upper right of the screen.
Marker Delta – Checking this box will display a second marker (Figure 12) and show the difference (delta) in frequency and signal
strength from the first marker.
Press the Enable Sweep button once to turn on the analyzer and press a second time to turn it off.
MURS Frequencies – Model 195M Only
The FCC has set aside five frequency channels in the VHF
band for Multi ‐ Use Radio Service (MURS) operation. By
operating on these frequencies and following the specific
rules such as limited power (2 Watts) and height (60 Feet),
the Model 195M can be used without obtaining an FCC site
license.
MURS Channels
Channel 1 – 151.820 MHz
Channel 2 – 151.880 MHz
Channel 3 – 151.940 MHz
Channel 4 – 154.570 MHz
Channel 5 – 154.600 MHz
Notes:
1. The highest point of any MURS antenna must not
be more than 18.3 meters (60 feet) above the
ground or 6.10 meters (20 feet) above the highest
point of the structure on which it is mounted.
2. RF output power is limited to 2 Watts
3. Repeater operation is not allowed.
The ESTeem Model 195M supports operation within the MURS frequency bands. Select the MURS tab in the configuration utility
(Figure 13) and set the frequency of operation. The output power of the modem will be set at 2 watts and the repeater
route/append table will be disabled.
